This article presents the computer-aided design of the intermediate and input/output cavities of a multi-beam klystron (MBK) working in the J-band frequency range. A coaxial type cavity has been proposed to meet the specified design parameters. The state of the art electromagnetic simulation tool Computer Simulation Technology microwave studio has been used for the design and optimization of the cavity. Different cavity parameters such as the quality factor, shunt impedance, etc. have been estimated with the help of the simulation tool. For the input/output cavities, the issue of symmetric coupling has been studied and a rectangular-shaped central conductor has been proposed to achieve the desired coupling.

SANTIGOPAL MAITYIn this paper, design of a high frequency Radial Reentrant Cavity (RRC) using commercially available three-dimensional (3D) electromagnetic simulation software is reported. The eigenmode analysis of the RRC structure has been carried out and a comparative study is done with reported reentrant cavities for relevant cavity parameters. The RRC structure can be used in klystron amplifiers operating in Ka-band (27-40GHz). This structure exhibits operating frequency of 31.6 GHz and a $\boldsymbol{R}/\boldsymbol{Q}$ value of $58.3\ \mathbf{\Omega}$ .

Chaitali KoleyV-band Klystrons find applications in satellite communications and 5G technology. Here, we present a V-band Klystron using radial re-entrant square cavities (RRSCs). The RRSCs are easy to fabricate, assemble, align, and tune to the operating frequency, which are significant concerns in V-band. We have optimized the number of cavities and the gap for best possible gain and bandwidth. The eigenmode and particle-in-cell (PIC) simulation results of the CST microwave studio are presented. The optimum design uses eleven equidistantly placed RRSCs, producing the maximum gain of 27.17 dB at 60.1 GHz with a bandwidth of ∼150 MHz.

Ayan Kumar BandyopadhyayKa-band frequencies are becoming increasingly popular due to their application potential in high-data-rate wireless communications relevant to 5G applications, satellite link establishment, etc. High-power amplifiers in this frequency band, offering several tens of watts of output RF power, are one of the main enabling components of these communication systems. This article reports the design studies and analysis of the radio frequency (RF) section of a multiple beam-extended interaction klystron (MB-EIK). The proposed multiple beam RF section with a ladder-type EIK structure offers several crucial features, such as a low-voltage operation, moderate operational bandwidth, and high output power. Starting from the design of the intermediate cavities, the input and output sections and the overall RF section are presented. The proposed RF section supports the operation at 28.5 GHz center frequency with about a 500 MHz 3 dB bandwidth employing four electron beams with a 4 kV DC accelerating field.

This article presents the design and simulation results for the RF section of a V -band klystron operating at 60 GHz. Square shape single side reentrant cavities, compatible with micromachining fabrication process are proposed for radio frequency (RF) section of this device. The cavity parameters were obtained through optimization of cavity geometrical parameters, i.e. the interaction gap, cavity length, height etc. Design approach of the cavities as well as corresponding simulation results are presented. Initial result of the beam wave interaction, showing stable growth of the RF wave is also presented. The license-free frequencies at V -band are being increasingly relevant with the advent of 5G mm-wave communication technologies. This device may find application in establishment of high data rate mm-wave communication for back-haul/front-haul.
