Integrated Circuit
FM, IF Amp/AFC & Meter Driver
Function:
FM Section:
IF Amp., Det., Driver for Tuning Meter
AM Section:
Conv., IF Amp
Features:
FM
Incorporates a Full
Balance Differential Circuit to Obtain Stable, High Gain in the IF Amplifying
Stage
Incorporates a Low
Distortion, Quadrature Detection Circuit
(0.3% distortion at 100% modulation).
The Tuning Meter’s Driver Voltage is Logarithmic to Input
AM
A High
Gain IF Amplifying Stage, with Input Level Allowable up to 100dB
μ
.
The Frequency Converting Stage Consists of a Single Transistor, while the Base, Emitter, and
Collector are Provided with Pins to Ensure Handling Ease.
