Hello Everyone;
What happens if we connect input of an RF power amplifier to matched load and output of it to an antenna (while it is powered on)?

i worked in this for sometime , if u connect a matched load and an anetnna to the PA , typically nothing will happen , ur PA will just get the DC
if there is some sort of coupling between input and output the amp may oacillate
when u try replace the antenna with matched load
be sure that ur DC is ok , then try to apply the RF signal to the input
also be aware of the VSWR from ur antenna , it is not matched to the PA ,
ur PA can be damaged
