MICRF010
QwikRadio® Low-Power UHF Receiver
General Description
The MICRF010 is a single chip, ASK/OOK (ON-OFF
Keyed) RF receiver IC recommended for new designs
replacing the MICRF007. It provides the same function with
sensitivity enhancement, typically 6dB better than the
MICRF007. Just like all other members of the QwikRadio^®
family, the MICRF010 achieves low power operation, a
very high level of integration, and it is particularly easy to
use.
All post-detection data filtering is provided on the
MICRF010, so no external baseband filters are required. In
fact, the entire receiver circuit is made of very few external
components and with the 8-pin SOIC package makes it
ideal for small printed circuit board area applications.
The MICRF010 works in fixed-mode (FIX) operation, which
functions as a conventional super-heterodyne receiver.
Fixed-mode provides better selectivity and sensitivity
performance in comparison with sweep mode used in other
Micrel receivers intended for lower cost applications.
