IF filter / amplifier / demodulator for FM
radio receivers
Preliminary specification
TEA6850
FUNCTIONAL DESCRIPTION
The first mixer stage at the input of the circuit is for mixing
the 10.7 MHz IF signal to 300 kHz. The IF filter has a
resonance frequency of 300 kHz (adjustable), tunable
from 50 kHz to 500 kHz, and a bandwidth of about 20 kHz
to 80 kHz tunable. Static filter response see Fig.5. The
limiter has a gain of approximately 90 dB, which is virtually
independent from temperature change. The demodulator
is frequency matched with the IF filter.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
