General Description
The NJM2287 is an IF Gain Control IC with 450kHz (standard) IF input,which operates from 2.7V to 5.5V supply. It includes a local-buffer, mixer,IF gain control amplifier, and RSSI circuit.The NJM2287 is especially designed for digital transceivers with built-in an analog gain control amplifier and a subsequent analog to digital converter circuit.The useful functions of the NJM2287 are rail-to-rail output swing of 3Vpp@3.3V and wide gain control of over 80dB. These features help streamline the subsequent circuit design.
