Description

1

RFIN

RF Signal Input. This pad is ac-coupled and matched to 50 Ω.

2, 12

Amplifier Gate Control. External bypass capacitors of 4.7 μF, 0.01 μF, and 100 pF are

required. ESD protection diodes are included and turn on below −1.5 V.

3, 4, 5, 9, 10, 11

Drain Bias for the amplifier. External bypass capacitors of 4.7 μF, 0.01 μF, and 100 pF

are required.

6

VREF

Reference Diode. Use this pin in combination with VDET. The voltage provides

temperature compensation to the VDET RF output power measurements.

7

RFOUT

RF Signal Output. This pad is ac-coupled and matched to 50 Ω.

8

VDET

Detector Diode Used for Measuring the RF Output Power. Detection via this 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.

Die Bottom

GND

Ground. The pads and die bottom must be connected to RF and dc ground.
