IF Amplifier
Detector Circuit
Low Noise Audio Amplifier
Signal Meter Circuit
Center Meter Circuit
Muting Circuit
AFC Circuit

AM
IF Amplifier
AGC Circuit

Features:
Labor Saving and Miniaturization are Possible, since the FM IF Amplifier Detection and AM IF
Amplifiers are Enclosed in the Same Package.
FM IF Amplifiers have High Stability due to the Adoption of the Full Balance Three Stage Direct
Coupled Differential Amplifier.
Utilizes the Quadrature Detection Circuit.
