Description
Interface Schematic
RF input internally matched to 50Ω. This input is internally AC-coupled.
Ground connection.
For nominal operation (High Power mode), V_MODE is set LOW. When
set HIGH, devices are biased lower to improve efficiency at lower out-
put levels.
Regulated voltage supply for amplifier bias circuit. In power down
mode, both V_REG and V_MODE need to be LOW (<0.5V).
No connection. Do not connect this pin to any external circuit.

RF output. Internally AC-coupled.
Output stage collector supply. Please see the schematic for required
external components.
Same as pin 10.

No connection. Do not connect this pin to any external circuit.
Interstage matching. Connect to pin 15.
First stage collector supply and interstage matching. A 4.7μF decou-
pling capacitor may be required. Connect to pin 14.
Power supply input for the DC bias circuitry.
Ground connection. The backside of the package should be soldered to
a top side ground pad which is connected to the ground plane with mul-
tiple vias. The pad should have a short thermal path to the ground
plane.
