The MXR-220S is a general purpose transceiver module that operates at 433.92MHz with typical sensitivity of -110dBm and is inteded for use in Part 15.231 systems. The MXR-220S functions as a superheterodyne transceiver 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 MXR-220S. Any one-of-four filter bandwidths may be selected externally by the user in binary steps, from 1.25kHz 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. The MXR-220S is a highly reliable wireless link with easy to control output power.
