NJM2294
FM IF IC FOR PAGER
■ 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.
