OPERATIONAL DESCRIPTION OF E966 The equipment under test (EUT) is the transmitter of E966 with multiband GSM (850/1900) ; WCDMA Band 2/4/5; 4G/FDD-LTE Band 2/4/5/7/17;

The majority of the phone circuitry consists: the VC7916-51 + VC7643-26 Power Amplifier \ the MT6177M RF transceiver \ MT6761V/WB Baseband Processor\

MT6357MRV/A+ MT6371P/A Power management unit. There is also a combination EMCP(KMQE60013M_B318,16GB+2GB). The system is powered by a rechargeable lithium-ion battery with a nominal voltage of 3.8 volts. The direct receiver(RX) contains all active circuits for the complete receiver chain supporting 3G WCDMA, and 2G GSM/GPRS mode reception. The path contains a total of 10LNAs(low Noise Amplifier),in which Two SAWless Rx input ports PRX 9/10 support for GGE (B2, B3, B5, and B8), TDSCDMA and TDD LTE (B34 and B39),1+1 sets of I/Q output. All transmitter characteristics are listed in this section. Typical specifications are for mid-band channel frequency and under typical operating conditions. Min/Max specifications are for extreme operating voltage and temperature conditions. TXO 4G 3G 2G BAND Supported FDD-LTE Band2/4/5/7/17 WCDMA Band2/4/5 2, 8(GSM) Direct Conversion transmitter (LTE/3G/8PSK) and DFM for GMSK o Dedicated power detection circuits for power control over specific power range o 2LB/2MB/1HB TX output port Hybrid DirectConversion (4G/3G/)/LowIF (GGE, DCHSDPA) receive All LNAS have balanced inputs and fully itegrated. The quadrature LO signal are generated by a divide-by-2 divider for high band(HB) LNAs and a divide-by-4 divider for low band(LB) LNAs. The RF signal is down converted by high/low band quadrature direct-down-conversion mixers. The analog baseband filter is a circuit, and a DC offset cancellation circuit(DCOC).The low-pass filter is configured as a 2nd-order Butterworth filter for 3G /4GFDD SC,3G /4G FDD DC. Receiver power ON/OFF sequence, LNA /band selection, total receiver gain including LNA, mixer and analog baseband and DCOC timing are controlled by digital circuit. In addition, IQ calibration is done by is done by injecting an offset frequency test tone generated by test tone generator(TTG) into the RX mixer. Addition on-the-fly IQ imbalance tracking may be added in the DBB without changing the receiver design. RF section also includes Bluetooth /WiFi/FM /GPS chips MT6631 Device features:

Bluetooth Features Compliant with Bluetooth 4.1+HS specification Bluetooth Piconet and Scatternet support support class1 operation with integrated power amplifier Receiver sensitivity: GFSK -94dBmDQPSK -93dBm8-DPSK -87.5dBm The baseband processor handles all physical layer radio control signals and network interfaces. The 32 KHz clock oscillator operates the baseband IC from a backup battery when the main battery is removed. The baseband processor is a Dual-core device that splits the processing between a DSP core and an ARM processor. The DSP handles the physical and layer 1 processing, while the ARM executes the layer 2 and layer 3 protocol and the man-machine interface (MMI). The Dual cores communicate through a dedicated block of dual port memory. It also communicates with the Subscriber Identity Module (SIM) through an interface to the mixed signal device. The baseband processor also communicates to the calibration system or external devices through a digital serial link that is available on the system connector. The other main signals on the system connector include the digital audio interface

(DAI) and allows for an external battery charging voltage. The MMI completes the phone design and includes the displays, keypads, vibration motor, speaker, microphone, and headset.

(g) Frequency hopping spread spectrum systems are not required to employ all available hopping channels during each transmission. However, the system, consisting of both the transmitter and the receiver, must be designed to comply with all of the regulations in this section should the transmitter be presented with a continuous data (or information) stream. In addition, a system employing short transmission bursts must comply with the definition of a frequency hopping system and must distribute its transmissions over the minimum number of hopping channels specified in this section.

(h) The incorporation of intelligence within a frequency hopping spread spectrum system that permits the system to recognize other users within the spectrum band so that it individually and independently chooses and adapts its hopsets to avoid hopping on occupied channels is permitted. The coordination of frequency hopping systems in any other manner for the express purpose of avoiding the simultaneous occupancy of individual hopping frequencies by multiple transmitters is not permitted.
