Generally...
video/RF amplifiers are measured the same.
Power output (undistorted and t 1db comprssion)?
Power gain (also votlage gain)
Distortion IMD, IP3, harmonics
Noise, noise figure of the amplifier.
You can use voltage gain or power gain so long as the input and output load
impedance are known.? For power the common use standard is 50 ohms and
DBW? or DBM.? Votage gain is sometimes used as well and if the load
impedance is know the conversion is easy math.??
That is an opamp amplifier so gain is the ratio of the feedback plus or minus 1.
The latter parts sign reflects if the amplifier is inverting or noninverting.
The series output resistors are for stability as most opamps are rather fussy
about reactive loads.? Fussy translated to they become unstable or can oscillate.
