■ GENERAL DESCRIPTION
NJM2294 is a super low current FM IF IC for pagers. It includes almost all functions of the paging IF system. In those functions, the RSSI function can be used for automatic gain control. When the electric field strength is high, the RSSI output signal can control the attenuation of an RF amplifier to improve the received condition.
