General Description
The MICRF213 is a general purpose, 3.3V QwikRadioยฎ Receiver that operates at 315MHz with typical sensitivity of -110dBm.
The MICRF213 functions as a super-heterodyne receiver for OOK and ASK modulation up to 7.2kbps. The down-conversion mixer also provides image rejection. All post-detection data filtering is provided on the MICRF213. Any one of four filter bandwidths may be selected externally by the user using binary steps (from 1.18kHz to 9.44kHz, Manchester Encoded). 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.
