ACT-100 TECHNICAL MANUAL REAGAN Attenuation. The RF AGC enumerator is used to provide a voltage controlled attenuation of the RF signal to prevent circuits downstream from functioning in a non-linear fashion. As bias current increases through PIN diodes CR and CR, their RF resistance decreases and the signal is attenuated. The RF resistance of CR connects the RF node of L32 and C101 directly to RF ground (C100).
® CUBIC. COMMUNICATIONS A member of he Cube Corporation family of companies [F AGC Attenuation, The IF AGC attenuation (C121 C170) is very similar to the RF AGC attenuation. The main differences are the frequency range (45 MHz instead of the aircraft band (118 137 MHz), and two sections instead of one. The IF AGC network alas contains three 90 degree phase shift networks (C121 C170).
ACT-100 TECHNICAL MANUAL Deteriorate. The IF signal into detector diodes CR6 and CR7 produce a ¥% wave rectified voltage for the AGC circuitry. Temperature compensation is accomplished by measuring the differential voltage of the detector diodes relative to 2 set of diodes with a fixed bias. A fast attack/slow decay integrator is used to quickly adjust the analog output level to allow capture of a DESKTOP signal.
