At the balanced mixer output (pins 37 and 38) there is a matching tank circuit (Cp
= 120 pF) for the following ceramic filter. The double filtered IF signal is amplified
in a preamplifier stage and then filtered again with a further ceramic filter. The
gain of the IF amplifier in the range from 16 dB to 26 dB may be set via a DC
level at pin 44 or bus controlled.
After passing the limiter amplifier the IF signal is demodulated. The MPX signal
is supplied at the output pin 54.
The IF_CENT output pin 2 (open collector) supplies a LOW level when the IF
frequency is in the preselected window. The IF_WINDOW output pin 3 (open
collector) is an information for too low or too high IF frequency.
