UTCMC3361BP
UTCMC3361BP is LOW VOLTAGE/POWER NARROW BAND FM IF manufactured by Unisonic Technologies.
DESCRIPTION
The UTC MC3361BP is designed for use in FM dual conversion munication. It contains a plete 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 munications and scanning receivers.
