APPLICATION NOTE
<FM SECTION>
ꢀ
RF amplifier (see Fig.1)
This stage is composed of the emitter-grounded
and cascade connection amplifier.
The input impedance of pin 16 is about 260Ω,
which is determined by D1.
ꢀ
Mixer amplifier (see Fig.2)
The amplified RF signal is transformed into
IF signal by the mixer circuit which is
composed of a differential amplifier.
The amplified IF signal is appeared through
the emitter follower circuit at pin 14. The
output impedance of the ceramic filter.
