AM - Receiver Circuit

Description

This is an efficient bipolar monolithic circuit to apply

in battery - powered or mains - operated radio

receivers up to 30 MHz. It contains controlled RF

stage, mixer, separated oscillator and regulated

multistage IF amplifier.

Features

• symmetrical structured circuitry

• controlled RF prestage

• multiplicative balanced mixer, separated oscillator

• very well implemented large - signal characteristic

begins already from 4.5 V supply voltage

• terminals for indicating instrument

• controlled IF amplifier implementing 60 dB control

range

• external demodulator (diode)

• wide range of supply voltage between 4.5 and 15 V
