AM - Receiver Circuit
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
