LOW POWER FM IF

No Preview Available !

Low Power Narrowband FM IF
. . . includes Oscillator, Mixer, Limiting Amplifier, Quadrature Discriminator,
Active Filter, Squelch, Scan Control, and Mute Switch. The MC3357 is
designed for use in FM dual conversion communications equipment.
Low Drain Current (3.0 mA (Typical) @ VCC = 6.0 Vdc)
Excellent Sensitivity: Input Limiting Voltage –
(– 3.0 dB) = 5.0 µV (Typical)
Low Number of External Parts Required
Recommend MC3372 for Replacement/Upgrade
