Product Description
QPA3333
The QPA3333 is a Power Doubler amplifier SMD Module.
The part employs GaAs MESFET, GaAs pHEMT and GaN
HEMT die and is operated from 45MHz to 1218MHz. It
provides excellent linearity and superior return loss
performance with low noise and optimal reliability. DC
current of the device can be externally adjusted for
optimum distortion performance versus power consumption
over a wide range of output level.
9 pin, 11.0 mm x 8.5 mm x 1.375 mm package
