stereo radio circuit. FEATURES. Wide supply voltage range: 1.8 or 2.1 to 12 V. Low current consumption: 15 mA at AM, 16 mA at FM. High selectivity with distributed IF gain. LED driver for stereo indication. High input sensitivity: 1.6 mV/m (AM), 2.0 mV (FM) for. 26 dB S/N. Good strong signal behaviour: 10 V/m at AM, 500 mV at FM.
The TEA5767HN is a single-chip electronically tuned FM stereo radio for low-voltage applications with fully integrated Intermediate Frequency (IF) selectivity and demodulation.
A stereo FM receiver has three major sections: Mono mode; Stereophonic mode; Section common to both mono and stereo modes; The section that is common to both mono and stereo modes is a standard FM receiver that recovers the modulating signal. The output of this section is routed to the remaining two sections.
It deals with aerials, stereo decoding, transmission and reception, stereo decoding, acoustics and speaker positioning, receiver adjusting and circuit analysis.
To make sure the FM-related functions work well, the FM mono, FM stereo, and FM RDS functions need to be tested in production. In this paper, we will discuss FM theory, FM stereo multiplexing and the RDS mechanism.
Stereo FM Transmitter using BA1404 IC - This is a stereo FM transmitter circuit using an IC from Rohmm semiconductors named BA1404 – which is a monolithic IC and has built in stereo modulator, FM modulator, RF amplifier circuitries.This FM modulator can be operated between 76 to 108Mhz.
