Abstract: One of the most important parts of radar modernization is radar transmitter high power amplifier (HPA). Modernized radar provides significant performance improvement: range, resistance to the electronic warfare (ECCM), moving target indication (MTI factor). In this paper, we design and propose the VHF-band high speed pulsed high power amplifier using four modules with MRF6V121KHR6 MOS FET. The construction and proposed technical solution of 2000 W radar amplifiers is tested and experimental evaluation showed the feasibility of radar transmitter modernization.

Keywords: Solid state radar transmitter, VHF-band MOS FET , High Power Amplifier (HPA).
