Test Circuit
Test Circuit and Application Information
The test circuit is based on the EVAL8 PCB Design.
Gerbers, the bill of material and complete schematic are
available at Micrel website:
(http://www.micrel.com/product-info/qwikradio.shtml).
EVAL8 provides the means for a complete evaluation of
the MICRF008YM. It is not intended as a final receiver
design. For final receiver applications, look for the RX8-x
series of reference designs. The board is a FR4
material, 0.062 inch thick, in two layers. It is strongly

recommended that all RF designs are made in a
minimum two-layer board, one side being as solid
ground as possible. Blank EVAL8 boards are available
for selected customers. To obtain a blank board contact
your
drawings are shown below, the top layer, bottom layer,
the top silkscreen layer, and the bottom silkscreen layer.
The size of the board is 0.910 x 0.760 inches. It provides
the means to test the part thoroughly.
