Abstract
This paper describes the design and development of of a Gallium Nitride (GaN) based Solid State Pulsed Power Amplifier (SSPPA). Pulsed Power amplifiers are the main building blocks for all pulsed RADAR systems. This paper dwells on the design of the RF section and an innovative design of a microcontroller and multivibrator based circuits to monitor, display and protect high power solid state amplifiers. This amplifier works in the X-band, generating a peak pulsed power of 50W, up to a duty cycle of 20%. This amplifier can be used as a basic building block to realize higher power amplifiers, which can replace microwave tubes.
