In this paper, the design and particle simulation of a Ka-band stagger tuned gyro-twystron amplifier is presented. The concept of stagger tuning in gyro-twystron improves the bandwidth along with high RF output power which is suitable for radar application. The complete amplifier structure is modelled in “CST particle studio” for studying the beam wave interaction behaviour. The PIC simulation predicted...
The generation of continuous THz-waves by photomixing has several promising features, such as extremely-wide frequency tunability, very narrow linewidth, good frequency stability, and the ability to transmit high-frequency signals through low-loss optical fibers. To make such a scheme work effectively, we developed an InP/InGaAs uni-traveling-carrier photodiode (UTC-PD) [1, 2]. The UTC-PD has a unique...
