MC3374 - Motorola

MC3374 LOW VOLTAGE SINGLE CONVERSION FM RECEIVER

The MC3374 is an FM narrowband receiver capable of operation to 75 MHz. The low voltage design yields low power drain and excellent sensitivity in narrowband voice and data link applications. In the typical application the mixer amplifies the incoming RF or IF signal and converts this frequency to 455 kHz. The signal is then filtered by a 455 kHz ceramic fil.
