Description

1, 2, 3, 11, 12, 13

VDD1, VDD3,

VDD5, VDD6,

VDD4, VDD2

Drain Bias for the Amplifier.

4, 10

VGG1, VGG2

Amplifier Gate Control. ESD protection diodes are included and turn on below −1.5 V.

5, 9

NIC

Not Internally Connected. Note that data shown herein was measured with the NIC pins externally connected to RF and dc

ground.

6, 8, 15, 17

GND

Ground Pins. Connect the GND pins and the exposed pad to RF and dc ground.

7

RFIN

RF Signal Input. The RFIN pin is ac-coupled and internally matched to 50 Ω.

14

VDET

Detector Diode Used for Measuring the RF Output Power. Detection via the VDET pin requires the application of a dc bias

voltage through an external series resistor. Used in combination with VREF, the difference voltage, VREF − VDET, is a

temperature compensated dc voltage proportional to the RF output power.

16

RFOUT

RF Signal Output. The RFOUT pin is ac-coupled and internally matched to 50 Ω.

18

VREF

Reference Diode Used for Temperature Compensation of VDET RF Output Power Measurements. Detection via the VREF pin

requires the application of a dc bias voltage through an external series resistor. Used in combination with VDET, this voltage

provides temperature compensation to VDET RF output power measurements.

EPAD

Exposed Pad. The exposed pad must be connected to RF and dc ground.
