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
