ABSTRACT:
Automatic power output control circuitry is disclosed in which the magnitude of a radio frequency signal is maintained at one of a plurality of magnitudes selected in response to control signals. The radio frequency signal output from a variable output amplifier is sampled and the sample is further amplified and the dynamic range compressed prior to being rectified. The rectified power magnitude signal, which is nonlinearly related to the radio frequency signal magnitude, is adjusted by an adjustment factor selected by the control signals and employed in varying the output of the variable output amplifier to produce a corresponding radio frequency signal output magnitude.
