• Description: One Chip Car Radio, AM/FM Receiver
• Manufacturer: Infineon Technologies Corporation

FS: 04/93
General Description
The TUA 4300 G is a one chip car radio system consisting of AM/FM receiver, AM-Up/Down conversion, AGC amplifier
/ demodulator, FM-IF limiter amplifier / demodulator and stereodecoder / noiseblanker.
1. AM/FM-Receiver
The TUA 4300 G is an integrated combined AM-FM-receiver with strictly symmetrical RF parts for use in car radios.
Features
2. FM Mode
A. FM-Receiver
In this mode, the receiverpart is comprised of a mixer, an oscillator, a prestage control and an IF post amplification.
Features
B. FM-IF Demodulator
The FM-IF-demodulator has been developed especially for car radio applications.
