UTCMC3361BP Datasheet, PDF (1/3 Pages) Unisonic Technologies – LOW VOLTAGE/POWER NARROW BAND FM IF

UTCMC3361BP 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.

*Excellent input sensitivity
(-3dB limiting, 2.0µVrms typ.)
*Minimum number of external components required.
*Operating Voltage:2.5~7.0V
APPLICATIONS
*Cordless phone (for home use)
*FM dual conversion communications equipment
