Mounting Instructions
1. Use a large ground pad area near device pins 1, 2,
4, and 5 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.

Function
RF IN
Description
RF input pin. This pin requires the use
of an external DC blocking capacitor
chosen for the frequency of operation.
Connection to ground. Use via holes for
best performance to reduce lead
inductance as close to ground leads as
possible.
