Pin-Out Description

Pin

Function

Description

1VBAT

Supply voltage for the bias circuitry.

2RF IN

RF input internally matched to 50

 and DC blocked.

3VMODE1

Digital control input for power mode selection.

4VMODE0

Digital control input for power mode selection.

5VEN

Digital control input for PA enable and disable.

6CPL OUT

Coupler output.

7GND

This pin must be grounded.

8CPL IN

Coupler input used for cascading couplers in series. Terminate this pin with a 50

 resistor if not connected to

another coupler.

9RF OUT

RF output internally matched to 50

 and DC blocked.

10

VCC

Supply voltage for the first and second stage amplifiers which can be connected to the battery supply or output

of the DC-DC converter.

Pkg

Base

GND

Ground connection - this package backside should be soldered to a topside ground pad connecting to the PCB

ground plane with multiple ground vias. The pad should have a low thermal resistance and low electrical imped-

ance to the ground plane.
