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.
