80350 Module Integration Guide 1.5 General Design Guidelines 1.5.1 Advanced tips for an RF friendly layout 1.5.1.1 Ground Plane When designing the 80350 module into the host application, special care must be taken regarding the design of grounding on the host PCB. Proper grounding of the module’ is an essential part of any good application, as it can very effectively keep EMI in check and ensure good heat dissipation.
80350 Module Integration Guide 1.5.1.2 Antenna and RF Signal Trace For best antenna performance, please ensure that the antenna’s RF trace be designed to be 50 ohm special impedance line, and that there are a sufficient number of ground holes around the antenna impedance line and connector. Keep other traces of the module and the host board as far from this impedance line as possible. It should be avoided that other traces run in parallel to or cross the antenna impedance line.
80350 Module Integration Guide The following picture shows an example of the power supply trace for the module. The trace covers the entire power pin of the module. The wide trace is intended to minimize voltage drop over the trace. .
80350 Module Integration Guide 1.5.2 Audio Reference Design 1.5.2.1 Audio schematics The audio quality is very much dependent on the circuit design and layout. As an aid to obtaining good audio quality, a reference design has been included below. 1． Please serially place a Bead on Audio In/Out (see in the following circuit: L100, L101, L102, L103, L106 and L107) in order to reduce GSM TDD noise. Bead (100MHz, R>=1K ohm) is recommended. 2． Add a small capacitor on each audio trace.
80350 Module Integration Guide 1.5.2.2 Audio Layout Audio signals are very weak and are in the category of weak analog signals; they are extremely susceptible to interference from digital signals. Therefore, it is suggested that audio signal traces follow the same layer differential trace layout method, and be kept far away from strong digital signals (e.g., power signal, RF related signal, CLK signal and high-speed Bus).
