Abstract
The tuner-IF system operates with three current mirrors. One current mirror accepts an AGC signal and develops an RF AGC voltage, another current mirror accepts the AGC signal and develops an IF AGC voltage and a third current mirror establishes a minimum IF gain for the system and allows for additional slight IF gain reduction for excessive incoming signals. The three current mirrors are of the Wilson type and enable flexibility in establishing crossover points, delay times between the tuner RF and IF gain reductions and the like.
