MICRF009 General Description

The MICRF009 is a single chip, ASK/OOK (ON-OFF Keyed) RF receiver IC. It provides the same function but with performance enhancements over earlier QwikRadio® receivers. Two key improvements are: higher sensitivity (typically 6dB higher than the MICRF002) and faster recovery from shutdown (typically 1ms). Just like all other members of the QwikRadio® family, the MICRF009 achieves low power operation, a very high level of integration, and it is particularly easy to use.

All post-detection (demodulator) data filtering is provided on the MICRF009, so no external baseband filters are required. One of two filter bandwidths may be selected externally by the user. The user only needs to program the appropriate filter selection based on the data rate and code modulation format.

The MICRF009 offer two modes of operation; fixed-mode (FIX) and sweep-mode (SWP). In fixed-mode the MICRF009 functions as a conventional superheterodyne receiver. In sweep-mode the MICRF009 employs a patented sweeping function to sweep a wider RF spectrum. Fixed-mode provides better selectivity and sensitivity performance while sweep mode enables the MICRF009 to be used with low-cost, imprecise transmitters.
