RF circuit layout principles

When designing the RF circuit layout, the following general principles must be satisfied first:

Isolate the high-power RF amplifier (HPA) and the low-noise amplifier (LNA) as much as possible. Simply put, keep the high-power RF transmitting circuit away from the low-power RF receiving circuit;

Make sure that there is at least one piece of ground in the high-power area of the PCB. It is best not to have vias. Of course, the larger the copper foil area, the better;

Circuit and power decoupling are also extremely important;

The RF output usually needs to be far away from the RF input;

Sensitive analog signals should be as far away from high-speed digital signals and RF signals as possible;
