Function Description
VREG_PCS
RFIN_PCS
Regulated voltage supply for PCS band amplifier bias circuit. In power
down mode, both V_{REG_PCS} and V_{MODE_PCS} need to be LOW (<0.5V).
PCS band RF input internally matched to 50Ω. This input is internally
AC-coupled.
VREG_Cell
VMODE_
Cell
Regulated voltage supply for Cell band amplifier bias circuit. In power
down mode, both V_{REG_Cell} and V_{MODE_Cell} need to be LOW (<0.5V).
Cell band mode control pin. For nominal operation (High Power mode),
V_{MODE_Cell} is set LOW. When set HIGH, devices are biased lower to
improve efficiency.
RFIN_Cell ^{Cell band RF input internally matched to 50Ω. This input is internally}
AC-coupled.
VCC1_Cell ^{Cell band first stage collector supply. A 2200uF and a 4.7μF decou-}
pling capacitors are required.
NC
No connection. Do not connect this pin to any external circuit.

VMODE_
PCS
PCS band mode control pin. For nominal operation (High Power mode),
VMODE_PCS is set Low. When set HIGH, devices are biased lower to
improve efficiency.
GND
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.
