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
-
High flexibility with an external preamplifier stage for AM and FM
-
Strictly symmetrical RF parts
-
Separate mixers for AM and FM mode
-
Sym. or asym. mixer inputs
-
Only one 2-pin-oscillator for the 1st LO (in AM mode the oscillator frequency is divided by 8 or 10)
-
1st LO with LC-tank circuit
-
1st LO at 100 MHz range
-
1st LO decoupled counter output
-
1st LO decoupled divided counter output
-
Low phase noise
-
FM/AM field strength output combined
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
-
Integrated AGC generation for PIN Diodes and MOSFETs
-
High level mixer input
-
High input/output 3.order interceptpoint
B. FM-IF Demodulator
The FM-IF-demodulator has been developed especially for car radio applications.
Features
- 7stage limiter amplifier
- Coincidence demodulator
- Field strength output (combined with AM)
- Fixed mute depth (with full muting typ 80dB)
- Multipath detector with analog output
