A solid RF layout requires careful planning of board stack-up, power supply routing, supply bypassing, and grounding. These techniques, along with correct placement of filter components, can address PLL spurs as demonstrated by an IEEE-902.11a/g transceiver reference design.
Fundamentals of supply routing and bypassing
When designing RF circuits, the implementation and layout of the power supply section is often treated as an afterthought when compared with the high-frequency signal path. Without careful consideration, it is easy for the supply voltages around the circuit to become corrupted and noisy, adversely affecting the system performance of the RF circuitry. Proper planning of the PCB layer stack-up, VCC routing via a star topology, and proper decoupling of the VCC pins will help in achieving the best RF performance possible.
