Pin

Function

Description

1GND

Connection to ground. Use via holes for best performance to reduce lead inductance as close to ground leads as possi-

ble.

2GND

Same as Pin 1.

3RF IN

RF input pin. This pin requires the ise of an external DC blocking capacitor chosen for the frequency of operation.

4VCC

Supply Connection. This pin should be bypassed with suitable capacitor(s).

5GND

Same as Pin 1.

6RF OUT

RF output and bias pin. DC voltage is present on this pin, therefore a DC blocking capacitor is necessary for proper oper-

ation.
