In this work, a 0.9-2.4 GHz, 25 Watt output power, radio frequency (RF)
power amplifier based on Class-E switchmode topology has been analyzed.
A load-pull simulations method is used to optimize the power performance
in the operating band. To design input and output matching networks an
optimized low pass filter network was used. Simulated results of the
power amplifier (PA) demonstrate wideband behavior which covers a 0.9
GHz to 2.4 GHz band with an efficiency of 32-78%, and an output power
of 25 W (44 dBm), and an average gain of 20 dB. The designed PA provides
attractive features associated with a wider band, high gain, and
efﬁciency, which makes it a proper candidate for the mobile transmitter
and cellular infrastructure applications.
