  • Description

    NJW2311 is the IC which has the automatic IF detection of FM modulating signal of the 1.5MHz to 15MHz, that operates from 4.5V, and makes unnecessary such as the phase-shifter which was conventionally required as external parts. An IF amplifier, a FM demodulator and a low noise Op-amplifier are built in. Since high S/N ratio and low distortion characteristics are realized, it is the best for the various FM Receivers of wireless or wired Voice communications.
