A Gysel Power Divider/Combiner with Enhanced Power-Handling Capability

Abstract

By increasing the impedance of the microstrip of the combine port, a new Gysel power combiner/divider (PCD) with enhanced average power-handling capability (APHC) was proposed. This article shows the simulated results of the traditional Gysel PCD and the proposed Gysel PCD at the center frequency of 2.4 GHz and 10 GHz. For verification, one example of the proposed Gysel PCD operating at 2.4 GHz was designed, fabricated, and measured. One traditional Gysel PCD operating at 2.4 GHz was also fabricated to compare the APHC of the proposed Gysel PCD and the traditional Gysel PCD, by means of measuring the temperature variation of the microstrip line at the same power. The measurement result suggests the APHC of the proposed Gysel PCD is nearly twice that of the traditional Gysel PCD.

A Novel Planar Power Divider/Combiner for Wideband High-Power Applications

“…On the other hand, Gysel power dividers (GPDs) have a higher power handling capability [18]. In comparison with Wilkinson power dividers, Gysel power dividers' use of grounded resistors is one of their advantages [19]. GPDs can handle more power by using grounded resistors, which transfer heat to the ground.…”
