Abstract—This paper describes the design and development of a narrow band two stage high speed Solid State Pulsed Power Amplifier (SS-PPA) working at 7.23 GHz frequency. The amplifier is designed by using commercial packaged PHEMTs. A pulse aggregate card has been developed to provide modulated pulsed bias. At room temperature, the PPA provides 17.58 dB gain yielding 26.58 dBm peak output power for 9 dBm input driving power. The measured rise and fall time of the final prototype is obtained as 25.0 ns and 19.2 ns respectively at 90 ns Pulse Width (PW) with 30 kHz Pulse Repetition Frequency (PRF). We report a description of the design of the amplifier along with an account of its performance made through a comparison of simulated and measured results with desired target specifications.
