The Applied Systems Engineering Model 117 is a pulsed Traveling Wave Tube (TWT) amplifier engineered for high-power microwave applications requiring precise RF pulse generation. Operating across 2.0 GHz to 18 GHz with peak power output of 1 to 2 kW, the unit delivers controlled pulse widths from 0.07 to 15 μs at pulse repetition frequencies up to 100 kHz, constrained by a 1.5% duty cycle. The amplifier generates shaped RF pulses without external RF switches—pulse width control is achieved through an external pulse input. Modular DC-DC converter-based high voltage power supplies provide exceptional stability, directly supporting optimal phase noise and spurious performance from the TWT. The modular construction grants straightforward access to internal components, simplifying maintenance and field upgrades.
