VISIT US: www.meigsmart.com MeiG-SLM900 Multi-network Smart LTE Module Support for Wi-Fi & BT functionality The equipment under test (EUT) is the smart module of Model SLM900(Model name). It supports Triple-bandGSM/GPRSsolution(GSM850 ,PCS1900),GPRS/EDGE Class 12 Triple-band UMTS (B2,B4,B5)HSDPACategory 24,HSUPACategory 6also supportsIEEE802.11a/b/g/n/acBluetooth version2.1+EDR,BT3.0+EDR,BT5.0,GPS operating frequency is 1.57542GHz. The Qualcomm device incorporates the UMTS/LTE technology the technology for RF transceivers(SDR660) that converts received signals directly from RF-to-baseband and transmits signals directly from baseband-to-RF (known as direct conversion or zero intermediate frequency (ZIF) processing). This technique eliminates the need for large IF surface acoustic wave (SAW) filters and supporting IF and LO circuits, thereby reducing the handset parts count and facilitating multiband, multimode handsets that can be produced in smaller form factors. RF transmitter The RF transmitters are capable to perform as well as UMTS and HSPAmodulation signals with excellent noise performance, thus no interstate filter in between transceiver and PA is required:

Triple-band UMTS, with one low band and two high bands selected from:

Low band Band 5 (826 to 836 MHz) High band Band 2 (1852 -1907 MHz) Band 4 (1712 -1752 MHz) Triple-band GSM Low band GSM 850 (824 to 849 MHz) High band PCS 1900 (1930 to 1989 MHz) MeiG-SLM900 Multi-network Smart LTE Module Support for Wi-Fi & BT functionality LTE Band 2/4/5/7/12/13/17/25/26 Band 2 (1850-1910 MHz) Band 4 (1710 -1755MHz) Band 5 (824 - 849 MHz) Band 7 (2500 - 2570 MHz) Band 12 (699-716MHz) Band 13 (777-787 MHz) Band 17 (704-716 MHz) Band25 (1820-1915 MHz) Band26 (814-849 MHz) The transmit signal paths include a shared set of baseband amplifiers, a dedicated quadrature upconversion for each band type (low and high), gain control RF amplification, and multiple output driver amplifiers for each band type. Three UMTS output drivers support one low band and Two high bands; LTE support Bands: 2/4/5/7/12/13/17/25/26 Numerous secondary Tx functions are also integrated: a reference for the transmit DACs, the Tx phase-locked loop (PLL), the Tx local oscillator circuit, the Tx LO generation and distribution circuits, an RMS Tx power detector, and various interface, control, and status circuits. The RF transmitter interfaces internally with the baseband circuits for its analog baseband input and status and control signaling. Power reduction features controlled by baseband circuits (such as selective circuit powerdown, gain control, and transmit puncturing) extend handset talk time. The driver amplifier outputs are routed externally to the final stages of the transmit chains, culminating with the antenna switch whose output drives the antenna. Sophisticated Tx LO circuits implement the frequency plan and are completely integrated on-chip. All Tx LO signals are generated by the on-chip Tx local oscillator under the control of its PLL.

The modular transmitter must have its own RF shielding. This is intended to ensure that the module does not have to rely upon the shielding provided by the device into which it is installed in order for all modular transmitter emissions to comply with FCC limits. It is also intended to prevent coupling between the RF circuitry of the module and any wires or circuits in the device into which the module is installed. Such coupling may result in non-compliant operation. The physical crystal and tuning capacitors may be located external to the shielded radio elements. 15.212(a)(1)(i)

- YES - NO(*) Details: <example The module contains a metal shield which covers all RF components and circuitry. The shield is located on the top of the board next to antenna connector>

2. The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with FCC requirements under conditions of excessive data rates or over-modulation. 15.212(a)(1)(ii)

- YES - NO(*) Details: <example Data to the modulation circuit is buffered as described in the operational description provided with the application>

3. The modular transmitter must have its own power supply regulation on the module. This is intended to ensure that the module will comply with FCC requirements regardless of the design of the power supplying circuitry in the device into which the module is installed. 15.212(a)(1)(iii)

- YES - NO(*) Details: <example The module contains its own power supply regulation. Please refer to schematic filed with this application>

4. The modular transmitter must comply with the antenna and transmission system requirements of 15.203, 15.204(b), 15.204(c), 15.212(a), and 2.929(b). The antenna must either be permanently attached or employ a unique antenna coupler (at all connections between the module and the antenna, including the cable). The professional installation provision of 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph 15.212(b). 15.212(a)(1)(iv)

- YES - NO(*) Details: <example The module connects to its antenna using an UFL connector which is considered a non-standard connector. A list of antennas tested and approved with this device may be found in users manual provided with the application>

5. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in Section 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module (see Section 15.27(a)). The length of these lines shall be length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment.

THIS MUST BE SIGNED BY THE APPLICANT/AGENT AND SHOULD BE PLACED ON APPROPRIATE LETTERHEAD Modular Approval Requirement 6. The modular transmitter must be labeled with its own FCC ID number, or use an electron display (see Requirement Met KDB Publication 784748). If using a permanently affixed label with its own FCC ID number, if the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: Contains Transmitter Module FCC ID: XYZMODEL1 or Contains FCC ID:

XYZMODEL1. Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. If the modular transmitter uses an electronic display of the FCC identification number, the information must be readily accessible and visible on the modular transmitter or on the device in which it is installed. If the module is installed inside another device, then the outside of the device into which the module is installed must display a label referring to the enclosed module. This exterior label can use wording such as the following: Contains FCC certified transmitter module(s). Any similar wording that expresses the same meaning may be used. The user manual must include instructions on how to access the electronic display. A copy of these instructions must be included in the application for equipment authorization. 15.212(a)(1)(vi)

- YES - NO(*) Details: <example There is a label on the module as shown in the labeling exhibit filed with this application. Host specific labeling instructions are shown in the installation manual .filed with this application.>

7. The modular transmitter must comply with all specific rule or operating requirements applicable to the transmitter, including all the conditions provided in the integration instructions by the grantee. A copy of these instructions must be included in the application for equipment authorization. For example, there are very strict operational and timing requirements that must be met before a transmitter is authorized for operation under Section 15.231.

SLM900(model name) Operational Description For WWAN The equipment under test (EUT) is the smart module of Model SLM900(Model name). It supports Triple-bandGSM/GPRSsolution(GSM850 ,PCS1900),GPRS/EDGE Class 12 Triple-band UMTS (B2,B4,B5)HSDPACategory 24,HSUPACategory 6also supportsIEEE802.11a/b/g/n/acBluetooth version2.1+EDR,BT3.0+EDR,BT5.0,GPS operating frequency is 1.57542GHz. The equipment under test (EUT) is the transmitter of SDR660, It supports LTE Band 2/4/5/7/12/13/17/25/26, Release 10,Cat 4 and not support CA. The module use Qualcomms SDM660 chip which include Digital Baseband controller, Analog Baseband controller and Modem Processing subsystems; The PMIC is PM660 Chip;

the UMTS and LTE Power Amplifier Modules are SKY77638-11, and SKY77912-

61,respectively. The remainders of the major radio components are the SAW filters, and crystal. There is also a combination PCM memory IC and other peripherals such as BT, and etc.. The system is powered by a rechargeable lithium-ion battery with a nominal voltage of 3.8 volts. The 38.4MHZsystem clock is generated by a 38.4MHz TCXO via PM660s clock Buffer, then connect to SDM660 Chip. The Qualcomm device incorporates the UMTS/LTE technology the technology for RF transceivers(SDR660) that converts received signals directly from RF-to-baseband and transmits signals directly from baseband-to-RF (known as direct conversion or zero intermediate frequency (ZIF) processing). This technique eliminates the need for large IF surface acoustic wave (SAW) filters and supporting IF and LO circuits, thereby reducing the handset parts count and facilitating multiband, multimode handsets that can be produced in smaller form factors. RF transmitter The RF transmitters are capable to perform as well as UMTS and HSPAmodulation signals with excellent noise performance, thus no interstate filter in between transceiver and PA is required:

Triple-band UMTS, with one low band and two high bands selected from:

Low band Band 5 (826 to 836 MHz) High band Band 2 (1852 -1907 MHz) Band 4 (1712 -1752 MHz) Triple-band GSM Low band GSM 850 (824 to 849 MHz) High band PCS 1900 (1930 to 1989 MHz) LTE Band 2/4/5/7/12/13/17/25/26 Band 2 (1850-1910 MHz) Band 4 (1710 -1755MHz) Band 5 (824 - 849 MHz) Band 7 (2500 - 2570 MHz) Band 12 (699-716MHz) Band 13 (777-787 MHz) Band 17 (704-716 MHz) Band25 (1820-1915 MHz) Band26 (814-849 MHz) The transmit signal paths include a shared set of baseband amplifiers, a dedicated quadrature upconversion for each band type (low and high), gain control RF amplification, and multiple output driver amplifiers for each band type. Three UMTS output drivers support one low band and Two high bands; LTE support Bands:2/4/5/7/12/13/17/25/26;

Numerous secondary Tx functions are also integrated: a reference for the transmit DACs, the Tx phase-locked loop (PLL), the Tx local oscillator circuit, the Tx LO generation and distribution circuits, an RMS Tx power detector, and various interface, control, and status circuits. The RF transmitter interfaces internally with the baseband circuits for its analog baseband input and status and control signaling. Power reduction features controlled by baseband circuits (such as selective circuit powerdown, gain control, and transmit puncturing) extend handset talk time. The driver amplifier outputs are routed externally to the final stages of the transmit chains, culminating with the antenna switch whose output drives the antenna. Sophisticated Tx LO circuits implement the frequency plan and are completely integrated on-chip. All Tx LO signals are generated by the on-chip Tx local oscillator under the control of its PLL. RF receivers For the main RX section the IC features7 RX inputs, which can be used for multi-mode receive, this means they can be used for LTE and UMTS according to the operating bands for each system. Triple-band UMTS, with one low band and two high bands selected from:

LTE Band 2/4/5/7/12/13/17/25/26:

Low band Band 5 (869-894 MHz) High band Band 2 (1932-1987MHz) Band 4 (2112-2152MHz) Band 2 (1930-1990 MHz) Band 4 (2110 -2155MHz) Band 5 (869 - 894 MHz) Band 7 (2620 - 2690 MHz) Band 12 (729-746MHz) Band 13 (746-756 MHz) Band 17 (734-746 MHz) Band25 (1930-1995 MHz) Band26 (859-894 MHz) The on-chip receive signal paths are functionally identical for each mode (UMTS or LTE) and each band type (low or high). The external circuitry includes the antenna switch module and a filter function, either a duplexer or a bandpass filter. All RF Rx inputs use a single-ended configuration to maximize common-mode rejection, Tx isolation, out-of-band suppression, and second-order intermodulation performance. The downconverters output drive analog baseband filters and buffer circuits that are programmed to support the active operating modes waveforms (WCDMA or LTE). The analog baseband signals are then digitized by analog-to-digital converters (ADCs) whose outputs are routed to the digital baseband circuits for further processing. Numerous secondary Rx functions are also integrated: Rx frequency synthesizers (each having their own PLL and local oscillator circuits), LO generation and distribution circuits, reference and clock circuits for the ADCs, and various interface, control, and status circuits. Power reduction features (such as selective circuit powerdown, gain control, and bias control) extend handset standby time. Like the Tx LO, all Rx LO circuits are completely integrated. All received LO signals are generated by the on-chip Rx local oscillators under control of their PLLs. For BT/WIFI The 3-in-1 module WCN3980 integrates Bluetooth , WLAN and in one chip.
