Broadband Linearization of Microwave Power Amplifiers

10th European Microwave Conference, 1980, 1980
In an 11 GHz link line system up to 7 TV channels shall be transmitted with SSB modulation from a single transmitter. The high linearity of the power amplifiers and the frequency converters required for that could be obtained by separate amplitude and phase pre-distortion of the radio signal.

Broadband switch power amplifier design

2015 IEEE 16th International Conference on Communication Technology (ICCT), 2015
In recent time, class-EF power amplifiers are promising for the high power added efficiency (PAE) by turning output matching network (OMN) to control the even and odd harmonics at the drain. High quality factor (Q) of output matching network in the circuit is required. So it is difficult to design a broadband high efficiency power amplifier.

10W ultra-broadband power amplifier

2008 IEEE MTT-S International Microwave Symposium Digest, 2008
We report the design and performance of an ultra-broadband power amplifier. It achieves 10 Watts output power with 21dB ± 1.5dB gain from 20 MHz to 3000 MHz. At lower frequencies from 20 to 1000 MHz the output power is 15 Watts with 22% efficiency. To achieve this performance, we employ a new design concept to control the device impedance and the power
