High-Performance Integrated Circuits for High-Gain FM-IF Systems

Two new high-gain FM-IF linear integrated circuits (IC's) are now commercially available. These devices provide the cost and performance advantages generally associated with integrated circuits and are well suited for all FM-IF applications including automobile radio. This paper describes the application and design feature of two circuits: a high-gain amplifier limiter RCA CA3076 and an RCA CA3075 FM subsystem which employs a newly developed differential peak-detection method.
