UTC MC3361BP LINEAR INTEGRATED CIRCUIT
LOW VOLTAGE/POWER NARROW
BAND FM IF
DESCRIPTION
The UTC MC3361BP is designed for use in FM dual
conversion communication. It contains a complete narrow
band FM demodulation system operable to less than 2.5V
supply voltage. This low-power narrow-band FM IF system
provides the second converter, second IF, demodulator. Filter
Amp and squelch circuitry for communications and scanning
receivers.
