TCA440

• DIP 16

Description

The TCA440/T 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
