The MICRF221 is a third generation QwikRadio®
receiver, offering all the benefits of Micrel's earlier
QwikRadio® products with significant improvements,
including: enhanced sensitivity, automatic duty-cycle
feature and RSSI output.
The MICRF221 is a super-heterodyne receiver,
designed for OOK and ASK modulation. The downconversion mixer also provides image rejection.
The MICRF221 receiver provides a SLEEP Mode for
duty-cycle operation and an enhanced, customer
programmable "WAKE" function. These features are
further combined into a wholly integrated "self-polling"
scheme that is ideal for low and ultra-low power
applications, such as RKE and RFID
All post-detection data filtering is provided on the
MICRF221 receiver. Any one of four filter bandwidths
may be selected externally by the user in binary steps,
from 1.25kHz to 10kHz. The user needs only to program
the device with a set of easily determined values based
on data rate, code modulation format, and desired dutycycle operation.
