Re: RF power amplifier
it is easy to check the stability of the power amplifier,follow the following steps:
1) link the signal source and the power amplifier and the attenuator with the spectrum analyzer.
2) set the power amplifier analyzer full span
3) then turn on your power amplifier and let the signal source shut down(no rf signal output)
4)observe the output of the spectrum analyzer
5)if the screen is clear(there is no spur frequency display),then your amplifier is stability,otherwise your amplifier is not unstability
ok,good luck
