Description/Abstract
In this technical report, the design of a high-frequency matching circuit is presented. This circuit is a transformer comprising a cascade of multisections of quarter-wavelength transmission lines. The transformer, also referred to as matching circuit, is implemented based on microstrip technology. The matching circuit is required to perform as a transition from a 10-Ω load to a 50-Ω source. Moreover, this transition is specified to have a return loss more than 20 dB over the entire S-band from 2 GHz to 4 GHz. Analytical model developed and verified by full-wave simulation results indicates that the design of a quarter-wavelength transformer with four sections satisfies required design specifications. In-house prototype unit is fabricated to validate design performance. The experimental and simulation results of microwave scattering parameters are in very good agreement within an acceptable degree of error.
