MICREL SEMICONDUCTOR  MICRF211AYQS  芯片, 接收器, 433.92MHz, 3V

The is a 3V QwikRadio® 433.92MHz Receiver operates at 433.92MHz with typical sensitivity of -110dBm. The receiver functions as a super-heterodyne receiver for OOK and ASK modulation up to 10kbps. The down-conversion mixer also provides image rejection. All post-detection data filtering is provided on the receiver. Any one-of-four filter bandwidths may be selected externally by the user in binary steps, from 1.25 to 10kHz. The user need only configure the device with a set of easily determined values, based upon data rate, code modulation format and desired duty-cycle operation.
