Vdd

Supply Voltage.

2, 4, 9, 11

GND

These pins and the exposed ground paddle

must be connected to RF/DC ground.

3, 10

RF1, RF2

These pins are DC coupled and matched to 50 Ohms.

Blocking capacitors are required.

Select value based on lowest frequency of operation.

5, 7, 8

ACG1, ACG2, ACG3

External capacitor to ground is required. Select value for

lowest frequency of operation. Place capacitor as close

to pins as possible.

6, 12, 13,

15, 16

N/C

The pins are not connected internally; however, all data

shown herein was measured with these pins connected to

RF/DC ground externally.
