[SiMI]

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
