A high power TEM to TE₁₀ mode converter with 70% bandwidth

Abstract

In the paper, the design and simulation of the TEM-TE10 wideband and high-power mode converter (MC) are investigated. The working frequency of the MC is in the frequency range of 4.3–8.8 GHz (68.7% bandwidth). Due to increasing the waveguide cross-section, the probability of the electrical breakdown dramatically reduces. Electrical breakdown may occur at very high-power outputs of the electromagnetic sources. The power-handling capacity of the MC is 2.34 GW, at the centre frequency.
