100w rf power amplifier circuit built with 2 bly94 transistors.
The higher the voltage across r e v e the more temperature stable the amplifier but the more power will be wasted in r e due to v e 2 r e as well as the decreased ac signal gain if r e is not bypassed by a low reactance capacitor.
Mainly it is referred as rf power amplifier owing to its use to amplify radio frequency signal or increase power at the input to give more power at the output.
