Mixed element wideband microwave amplifier design via simplified real frequency technique

Abstract

In this study, we illustrate the design and implementation of a wideband microwave small-signal amplifier composed of mixed elements. The design is based on Simplified Real Frequency Technique (SRFT). A design of low power amplifier circuit is completed and its simulations are performed in success. The circuit is designed with lumped elements, however, some of the lumped elements are converted to distributed elements for their convenience in production. In this way, a mixed element wideband microwave amplifier comprised of input/output matching networks with lumped and distributed elements has been formed. Layout work and also post layout simulation is given with satisfying results.

Design of a multi-octave power amplifier with a novel broadband design methodology

“…It can automatically fulfill the broadband matching circuit design according to the set target parameters which has universality. In [18], a 42% bandwidth PA from 1.9 GHz to 2.9 GHz is designed by using the traditional SRFT to optimize the design of broadband matching circuit [23,24,25,26], which just considers the perspective of optimal impedance. In [27], by taking the efficiency index into account in the real frequency method, the proposed PA has a 1.8 GHz-2.7 GHz (40%) bandwidth with a 64-81% drain efficiency.…”
