Note: All capacitors are standard 0402 multi layer chip
Note 1: Using a hi-Q capacitor will increase efficiency slightly

Instead of a stripline,
an inductor of ~6 nH
canbeused

Distance between
edge of device and
capacitor is 0.240" to
improve the "off"
isolation
Distance between
edge of device and
capacitor is 0.080"
Instead of a stripline, an
inductor of 2.2 nH can
be used
