Default heat sink for rf ground?


The amp I'm building with the erf7530 s uses a solid copper board as the common ground. Right but it's feed backing like crazy so I'm going back through the circuit and doing soon tweaking. I read somewhere that i can use the heat sink for the rf ground and tie the source pins to it to help with feed back and oscillation. If i do this should i also tie the coax shield to the heat sink? If i do this do i need to tie it into dc ground with a capacitor, or will it be good enough for the source pins?
