Mounting Instructions
1. Use a large ground pad area under device pins 2
and 4 with many plated through-holes as shown.
2. We recommend 1 or 2 ounce copper. Measurements
for this data sheet were made on a 31 mil thick FR-4
board with 1 ounce copper on both sides.

Pin # Function
Description
1
RF IN RF input pin. This pin requires the use
of an external DC blocking capacitor
chosen for the frequency of operation.
2, 4 GND Connection to ground. Use via holes
for best performance to reduce lead
inductance as close to ground leads as
possible.
3 RF OUT/ RF output and bias pin. DC voltage is
BIAS present on this pin, therefore a DC
blocking capacitor is necessary for
proper operation.
