An FM radio on a single chip requiring only a few simple peripheral components. In particular the ship requires only one simple coil and alignment is very easy. The chip includes an RF input stage, mixer, local oscillator, IF amplifier/limiter, phase demodulator, mute detector and mute switch. The output will directly drive a crystal earpiece or could be used with a TBA820M to form a complete portable radio.
FM radio with TDA7000

Graph shows AF output voltage(Vo) and total harmonic distortion (THD) as a function of the emf input voltage (EMF) with a source impedance (Rs) of 75ohm : (1) muting system enabled; (2) muting system disabled. Note that the muting system can be disabled b
