In radar applications there is a need for high power amplifiers. This paper describes the design and performance of a pulsed solid state amplifier for radar transmitters. The amplifier is designed of four cascaded commercial amplifiers (Excelics 8 W Internally Matched Power FET; EIA 1616-8P) with micro strip technology on Rogers laminate RO3000. The amplifier works in frequency range 15.5 to 17.5 GHz. The drain voltage is pulsed by a pulse aggregate also designed at Saab Bofors Dynamics. In pulse mode the output power is 10 W (40 dBm) in the frequency range 15.5 to 16.5 GHz and the gain is about 20 dB. In this paper we describe the amplifier design and performance. We also show the results from simulations and measurements during the design stage and discuss the problems we had.
