DC - 40 GHz

Pin Number

Function

Description

Interface Schematic

1, 2, 14

ACG2

Low frequency termination. Attach bypass

capacitor per application circuit herein.

ACG1

Low frequency termination. Attach bypass

capacitor per application circuit herein.

RFOUT & VDD

RF output for amplifier. Connect DC bias (VDD) network

to provide drain current (Idd). See application circuit

herein.

3

VGG2

Gate control 2 for amplifier. Attach bypass

capacitors per application circuit herein. For normal

operation +3.5V should be applied to Vgg2.

6

RFIN

This pin is DC coupled and matched

to 50 Ohms. Blocking capacitor is required.

9

VGG1

Gate control 1 for amplifier. Attach bypass

capacitors per application circuit herein. Please

follow “MMIC Amplifier Biasing Procedure”

application note.

10

ACG4

Low frequency termination. Attach bypass

capacitor per application circuit herein.

11

ACG3

Low frequency termination. Attach bypass

capacitor per application circuit herein.

5, 7, 13, 15

GND

These pins and exposed ground paddle must be

connected to RF/DC ground.

4, 8, 12, 16

N/C

These pins are not connected internally; however, all data

shown herein was measured with these pins connected to

RF/DC ground externally.
