In this work a new hexagonal shape compact elliptical low pass filter (LPF) is introduced. To improve and extend the stop band, two additional transmission zeros are created by introducing three semi-circular slots in the ground plane. Insertion loss is <0.85dB in the range of 0-1.5 GHz within the pass band and return loss is >18 dB in the entire pass band. Rejection band is extended up to >20...
In this paper, design of the interaction circuit for a 95 GHz sheet-beam extended-interaction klystron (EIK) with uniform magnetic focusing is presented. Simulations with CST-3D PIC indicates peak RF output power of 10 kW is feasible with a 3.3 A, 19.5 kV beam. The beam shows good confinement without any beam interception.
Nonlinear analysis of a high-power gyro-TWT amplifier operating in TE01 mode has been investigated through particle-in-cell (PIC) simulation using CST-studio. The simulation results are validated against published results with close accuracy. The simulation predicts 150 kW output power at 34 GHz with 21% efficiency, 48 dB saturated gain and 1.3 GHz bandwidth.
