SGA5486Z

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. For optimum RF performance, use via holes as close to ground leads as possible to reduce lead

inductance.

2, 4

GND

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

ation.

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.
