MICRF211
3V, QwikRadio ? 433.92 MHz Receiver
General Description
Features
The MICRF211 is a general purpose, 3V QwikRadio
Receiver that operates at 433.92MHz with typical
sensitivity of -110dBm.
The MICRF211 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 MICRF211. 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
