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