Description
RF input internally matched to 50Ω. This input is internally AC-coupled.
Interface Schematic
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 output 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 exter-
nal 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 decoupling
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 multiple
vias. The pad should have a short thermal path to the ground plane.
