Abstract

This paper presents a hybrid Broadband power amplifier which provides high drain efficiency. AB and J, Two Classes of power amplifier are described using GaN HEMT with matching networks together with input and output compact elements. Using Load Pull method, the best input and output network in the central frequency of 3GHz for output power of 40dBm, 10dB high gain and high efficiency of 80%, has been designed. After describing the design of each of the amplifiers and comparing their performance, the proposed circuit, two-class AB/J are discussed to be the target of the circuit design, reducing the input power to achieve high efficiency output power and gain. Input and output matching proposed circuit elements in terms of theory and simulation are compared, and the results of both investigations were similar. Also, the fundamental harmonic and the second harmonic in the 0.5GHz bandwidth have the desirable amplitude of the output signal.
