FIBOCOM SQ808-NA Hardware Guide Page 9 of 78 Federal Communication Commission Interference Statement This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 1 This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures:
1 Reorient or relocate the receiving antenna. 2 Increase the separation between the equipment and receiver. 3 Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. 4 Consult the dealer or an experienced radio/TV technician for help. FCC Caution:
1 Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. 2 This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. This device is intended only for OEM integrators under the following conditions:
1) The antenna must be installed such that 20 cm is maintained between the antenna and users, and the maximum antenna gain allowed listed in Table 1-1 Max allowed antenna gain table. 2) The transmitter module may not be co-located with any other transmitter or antenna. As long as 2 conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed. IMPORTANT NOTE: In the event that these conditions can not be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product. In these circumstances, the OEM integrator will be responsible for re-
evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. End Product Labeling This transmitter module is authorized only for use in device where the antenna may be installed such that 20 cm may be maintained between the antenna and users. The final end product must be labeled in a visible area with the following: Contains FCC ID: ZMOSQ808NA. The grantee's FCC ID can be used only when all FCC compliance requirements are met. Manual Information To the End User The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the users manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual. Reproduction forbidden without Fibocom Wireless Inc. written authorization - All Rights Reserved.

The input range of power is 3.5V~4.2V and the recommended value is 3.8V. The performance of the power supply such as its load capacity, ripple etc. will directly affect the operating performance and stability of the module. In extreme cases, the peak current of the module can reach 3A and if the power supply capacity is insufficient that VBAT transient voltage drop below 3V, the module may be powered off or restarted. The VBAT voltage drop is shown as the following figure:
Figure 3-1 VBAT voltage drop 3.1.1 Power Input External power source supplies the module by VBAT pins. To ensure the power transient voltage is no less than 3V, it is recommended to connect two 220F tantalum capacitors with low ESR and decoupling capacitors of 1uF, 100nF, 39pF and 33pF in parallel to the VBAT input of the module. Besides the PCB trace of VBAT should as short and wide as possible (wider than 3mm) and the ground plane of the power section should be flat. That can reduce the equivalent impedance of the VBAT trace and ensure at maximum transmit power, significant voltage drop will not occur at high currents.

MIPI_CSI is a high-speed signal which has relatively high requirement for routing and must be prioritized 1) MIPI is a high-speed signal. It is recommended to connect the common mode inductor in series near the camera connector to reduce the electromagnetic interference of the circuit;
2) MIPI routing is recommended to be in the inner layer, with three-dimensional grounding;
3) The MIPI signal need to be controlled with a differential impedance of 90ohms and an error of 10%;
4) The total length of the trace does not exceed 300mm;
5) The intra lane match of MIPI signal must be controlled within 0.67mm;
6) The inter lane match of MIPI signal must be controlled within 1.3mm;
7) It is recommended that the space of intra lane should be 1.5 times trace width and the differential cable should keep 3 times trace width from other cable;
8) CAM_CLK is a high-speed clock signal and requires three-dimensional grounding;
9) The CAM AVDD power supply routing should be away from interference sources, otherwise it is easy to bring interference of power noise;
10)CAM AVDD power supply suggest to add LDO with high PSRR ability;
11) If the front and rear cameras share the I2C, it need to confirm that the I2C addresses of the two cameras do not conflict.

Microstrip trace is recommended for RF trace, with insertion loss within 0.2dB and impedance at 50ohms. A -type circuit is reserved between the module and the antenna connector (or feed point) for antenna debugging. Two parallel components are directly connected across the RF trace and should not pull out a branch, as the figure shows:

Common active antennas supply power from 3.3V to 5.0V. The active antenna itself consumes very little power, but requires a stable and clean power supply. It is recommended that a high-performance LDO be used to power the antenna. The active antenna gain requirement is <17db. If the gain is> 17db, the reserved

FIBOCOM SQ808-NA Hardware Guide Page 58 of 78 5 RF PCB Layout Design Guide For user PCB, the characteristic impedance of all RF signal traces should be within 50ohms. In general, the impedance of the RF signal trace is determined by the dielectric constant of the material, the trace width (W), the ground clearance (S) and the height of the reference ground plane (H). The control of the characteristic impedance of the PCB usually in two ways: microstrip trace and coplanar waveguide. To illustrate the design principles, the following figures show the structural designs of microstrip trace and coplanar waveguide when the impedance cable is at 50ohms.

The impedance simulation tool should be used to accurately control the RF signal cable at 50ohms The GND pin adjacent to the RF pin should not have thermal welding plate and should be in full impedance. contact with the ground. The distance between the RF pin and the RF connector should be as short as possible. At the same time, avoid the right-angle route. The recommended route angle is 135 degree. Attention should be paid to the establishment of the component package and the signal pin should be kept at a certain distance from the ground. The reference ground plane of the RF signal trace should be entirety; adding a certain amount of ground holes around the signal and the reference ground can help improve the RF performance; the distance between the ground hole and the signal trace should be at least 2 times the trace width

In the process of R&D, production assembly and testing, especially in product design, ESD protection measures should be taken. For example, anti-static protection should be added at the designed circuit interface and the points susceptible to electrostatic discharge or impact. Anti-static gloves should be worn during production.

The multislot class defines the maximum rate of uplink and downlink. The expression is 3+1 or 2+2, the first number represents the number of downlink timeslots and the second number represents the number of uplink timeslots. Active timeslot represents the total number of timeslots that the GPRS device can use for both uplink and downlink communications.
