The SAMP090950-60P is a 9 to 9.5 GHz pulsed amplifier that can deliver up to 1000W peak output power and related RF performance under all specified temperature and environmental conditions. This compact module utilizes the latest high power RF GaN HEMT transistors and also features built-in control and monitoring, with protection functions to ensure high availability.
Designed as the "pulse heart" of modern radar transmitters, electronic warfare (EW) jamming systems, and high-power RF test benches, the SAMP090950-60P supports ultra-flexible pulse widths from 200 ns to 200 μs at duty cycles up to 20%. It replaces legacy vacuum-tube TWT amplifiers — offering instant-on operation (zero warm-up), 100,000+ hour service life, superior linearity, and intelligent RS485 remote control.
