PCB Layout Information
The MICRF002 evaluation board was designed and
characterized using two sided 0.031 inch thick FR4
material with 1 ounce copper clad. If another type of printed
circuit board material were to be substituted, impedance
matching and characterization data stated in this document
may not be valid. The gerber files for this board can be
downloaded from the Micrel website at www.micrel.com.
