NJM2287

NJM2287 100MHz INPUT MIXER AND 450kHz IF GAIN CONTROL IC 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.
