The MAGB-103438-020S0P is a GaN HEMT D-mode
amplifier pair designed for use as a quadrature
combined or symmetrical Doherty driver amplifier in
base station applications in the frequency range of
3.4 - 3.8 GHz with modulated signal operation. This
device supports pulsed and linear operation with
peak output power levels to 25 W (44.1 dBm) in a
plastic package.
