1DB GAIN COMPRESSION AND SATURATED
OUTPUT POWER
The 1dB gain compression is a measurement of the output power
level where the small-signal insertion gain magnitude decreases
1dB from its low power value. The decrease is due to nonlinearities
in the amplifier, an indication of the point of transition between
small-signal operation and the large signal mode.
The saturated output power is a measure of the amplifier’s ability to
deliver power into an external load. It is the value of the amplifier’s
output power when the input is heavily overdriven. This includes the
sum of the power in all harmonics.
INTERMODULATION INTERCEPT TESTS
The intermodulation intercept is an expression of the low level
linearity of the amplifier. The intermodulation ratio is the difference in
dB between the fundamental output signal level and the generated
distortion product level. The relationship between intercept and
