Application Example
315MHz Receiver/Decoder Application
Figure 8 illustrates a typical application for the MICRF009
UHF Receiver IC. This receiver operates continuously (not
duty cycled) in sweep mode, and features 6-bit address
decoding and two output code bits.

Operation in this example is at 315MHz, and may be
customized by selection of the appropriate frequency
reference (Y1), and adjustment of the antenna length. The
value of C4 would also change if the optional input filter is
used. Changes from the 1kbps data rate may require a
change in the value of R1. A bill of materials accompanies
the schematic.
