This paper describes fabrication and experiment of 1.5 kW pulsed solid-state power amplifier (SSPA) with automatic gain equalization circuit for radar application. The 1.5 kW pulsed SSPA consists of two RF power amplifier module (PAM). Each RF power amplifier module has a series 8-cascaded power amplifier. Final RF output power is combined by hybrid ring combiner. Overall dimension of Pulsed SSPA...
This paper describes fabrication and experiment of a 1.5 kW solid-state pulsed power amplifier with automatic gain equalization circuit for radar application. The solid-state pulsed power amplifier consists of parallel RF power modules to obtain a high RF power of more than 1.5 kW. Each power module has a series 8-cascaded power amplifier. Overall dimension of the amplifier is 39x29x15.6cm3 . Experimental...
The vaned helix TWT for MPM application is designed, fabricated and tested to develop a wideband microwave source. The phase velocity and interaction impedance of a vaned helix circuit shown is predicted by use of the high frequency structure simulation (HFSS) code. To predict nonlinear performance of the vaned helix TWT, we utilize LMsuit code, which is a 1-D non-linear simulation code. From the...
