Application Example
315MHz Receiver/Decoder Application
Figure 10 illustrates a typical application for the MICRF007
UHF Receiver IC. This receiver operates continuously (not
duty cycled) in fixed-mode, and features 6-bit address decod-
ing and two output code bits.

Operation in this example is at 315MHz, and may be cus-
tomized by selection of the appropriate frequency reference
(Y1), and adjustment of the antenna length. Changes from
the 1Kbps data rate may require a change in the value of R1.
