Amplifier

June 1, 2012

Applied System Engineering (Fort Worth, TX) offers the Model 176X/Ku TWT amplifier that provides up to 2 Kilowatts at duty cycles up to 6% from 1.0 to 18 GHz, and pulse widths up to 100 μseconds. It is designed to operate pulsed traveling wave tubes in the 1- to 2-kW peak power range at frequencies up to 18 GHz. Generation of the output RF pulse shape is achieved without the use of RF switches. Pulse width control is with an external pulse. Internal power supplies are DC-DC converter designs with fast loop response times so that output level variations are minimal for any PRF, including a non-periodic or burst type PRF. The modular power supplies and grid pulse generator have low ripple, with attendant low phase noise in the amplifier.
