The Micrel MICRF022BM-FS24 is a ASK, OOK RF Receiver IC. It is part of MICRF022 family. This device is a true "antenna-in to data-out" monolithic device. All RF and IF tuning is accomplished automatically within the IC which eliminates manual tuning and reduces production costs. The result is a highly reliable yet low cost solution. The MICRF022 is packaged in 8-pin packaging. All IF filtering and post-detection (demodulator) data filtering is provided within the MICRF022, so no external filters are necessary. The MICRF022BM-FS24 features a Shutdown pin, which may be used to turn the device off for duty-cycled operation. This feature makes the it ideal for low and ultra-low power applications, such as RKE and remote controls. It has a demodulator filter bandwidth of 2500Hz. The MICRF022BM-FS24 offers fixed-mode (FIX) operation. In fixed mode it functions as a conventional superhet receiver. Fixed-mode provides better selectivity and sensitivity performance and sweep mode enables the MICRF022 to be used with low cost, imprecise transmitters.
