Sorry, but i have a question, is power plane same as ground plane?!

thanks in advance,
Ahmad,

Actually not .. power and ground planes are two different things ..
Power routing with a star topology, and proper decoupling of the power(Vcc) pins will help achieve the best RF performance possible ..

However, a single solid ground plane in a multi-layer stack-up board works well. The general rule is to avoid cross-interference by using a ground plane to shield the RF section from other circuitry in the board ..

On the other hand, there are no unique solutions to ground distribution in RF board design. Split ground planes or split traces can be utilized to separate analog and digital signals or to isolate high-current or high-heatgenerating sections ..
