SL621 AGC GENERATOR DS3631 - 1.0 The SL621C is an AGC generator designed specifically for use in SSB receivers in conjunction with the SL61OC, SL611C and SL612C RF and lF amplifiers.
In common with other advanced systems it generates a su itable AGC voltage directly from the detected audio waveform, provides a ‘hold’ period to maintain the AGC level during pauses in speech, and is immune to noise interference.
In addition it will smoothly follow the fading signals characteristic of HF communication.
