Typical Application

Micrel

Figure 7 below illustrates a typical application for the MICRF003 UHF Receiver IC. Operation in this example is at 915MHz,

and may be customized by selection of the appropriate reference frequency (CR1), 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. The Bill of Materials is shown in the accompanying chart.
