A Wilkinson power divider/combiner with enhanced power-handling capability

Abstract

This letter proposed a new Wilkinson power combiner/divider (PCD) with enhanced average power-handling capability (APHC) by decreasing the impedance of the microstrip of the combine port. For verification, one example of the proposed Wilkinson PCD operating at 2.3 GHz was designed, fabricated and measured to verify the proposed theory. One traditional Wilkinson PCD operating at 2.3 GHz was also fabricated to compare the APHC of the proposed Wilkinson PCD and the traditional Wilkinson PCD, by means of measuring the temperature variation of the microstrip line at the same input power. The measurement result of the temperature variation suggests the APHC of the proposed Wilkinson PCD is nearly twice that of the traditional Wilkinson PCD.

A large-transverse-size short-pulse 4-way power divider with high fidelity

“…UWB power divider (PD)/ synthesizer, as an essential component for power dividing or synthesizing in circuits or space, should not only behave high transmission efficiency, high waveform fidelity, but also should be as compact as possible [6,7,8,9]. When input by high-power signals, the impedance distribution of the transmission system is limited [10], the transmission line can adopt all-metal structure [11,12,13] or coaxial line with large transverse size [14,15]. The PD described in [16,17,18,19,20] showed advanced circular symmetry and their main ports were divided to more than 8 branches, which earned excellent transmission performance.…”
