Abstract
This article presents an unequal Gysel power divider (UGPD) based on circuit transformation, which is converted from a - to a T-type circuit. The -type circuit of a conventional unequal Gysel divider consists of two different value resistors and its connection transmission line. In the proposed T-type circuit, the dummy transmission line and the other transmission line with shunt resistor at center position is connected in parallel. Theoretical analysis was performed to derive the design equations for the proposed circuit conversion. For the validation of the circuit transformation, the UGPD using a T-type circuit at the center frequency of 2 GHz was fabricated and measured. The measured characteristics agreed well with the simulation results. (c) 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1529-1531, 2015
