MICROCHIP MICRF010YM-TR

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.
