Description
First stage collector supply. A low frequency decoupling capacitor
(e.g., 1 F) is required.
RF input internally matched to 50 . This input is internally AC-coupled.
Regulated voltage supply for amplifier bias. In Power Down mode, both
V
For nominal operation (High Power Mode), V
set HIGH, devices are turned off to improve efficiency.
Output stage collector supply. A low frequency decoupling capacitor
(e.g., 1 F) is required.
RF output internally matched to 50 . This output is internally
AC-coupled.
Ground connection. Connect to package base ground. For best perfor-
mance, keep traces physically short and connect immediately to
ground plane.
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.
