Pin

Function

Description

1VBAT

Supply voltage for bias circuitry and the first stage amplifier.

2RF IN

RF input internally matched to 50

 and DC blocked.

3VMODE1

Digital control input for power mode selection (see Operating Modes truth table).

4VMODE0

Digital control input for power mode selection (see Operating Modes truth table).

5VEN

Digital control input for PA enable and disable (see Operating Modes truth table).

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 second stage amplifier which can be connected to battery supply or output of DC-DC con-

verter.

Pkg

Base

GND

Ground connection. The 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.
