Ultra-Wideband Power Amplifier Design

Abstract: Power Amplifiers (PA) are large-signal amplifiers. This means that a large part of the load-line is used during signal operation. PAs are normally used as the last stage of communication electronics to provide large enough signals to be transmitted. This thesis describes the design of an ultra-wideband power amplifier. As the first part of this thesis, the power amplifier design is presented. In the second part of the thesis a printed circuit board (PCB) was designed and together with the designed circuit tested. The amplifier was designed to have an output of 5 W delivered at the frequency band from 500 MHz to 1 GHz with a gain of 15 dB.
