Based on the resonant cavity model, this paper presents a modeling approach for power/ground planes with decoupling capacitors. A bare plane pair is first modeled by the resonant cavity model. Then, decoupling capacitors are divided into segments according to port coefficients, capacitance, the number of decoupling capacitors, and the frequency response of each mode of the resonant cavity model. To...
The design and analysis of a wideband coupled-cavity Traveling-Wave Tube (TWT) operating at 35 GHz is presented. The interaction circuit employs a novel coupled-cavity circuit, which is based on the combination of a three-slot ladder coupled-cavity slow-wave structure and round electron beam. In this paper, the high frequency properties such as dispersion characteristics, beam-wave interaction impedance...
The V-band frequency range is a region of the millimeter-wave spectrum that has been developed for inter-satellite communications. A 100 W V-band coupled-cavity traveling-wave tube (CCTWT) is designed using High Frequency Structure Simulator (HFSS) and particle-in-cell (PIC) code in CST Particle Studio. Hot-test simulations show that the designed V-band CCTWT produces saturated output power over 100...
