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.
Part Identification Marking
The part will be marked with an A64 designator on
the top surface of the package.

Caution: ESD sensitive
Appropriate precautions in handling, packaging
and testing devices must be observed.
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. For optimum RF
performance, use via holes as close to
ground leads as possible to reduce lead
inductance.
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.
