This line of Traveling Wave Tube (TWT) Amplifiers ranges in power from 5 W CW to 50 kW pulsed and over frequencies from 1 GHz to 96 GHz. The CW amplifiers are typically in octave bandwidths, and pulsed amplifiers cover multi-octave and narrow band frequency ranges that reflect the current TWTA lines in production by various TWT manufacturers. The power supplies in the amplifiers use patented technology to provide the quietest RF amplification without introducing spurious signals. Unlike flyback and feed-forward circuits, these solid-state quasi-resonant switch mode supplies operate without high-power square waves. This results in less EMI/RFI amplified by the TWT and greater reliability because of reduced stress on the magnetic and semiconductor components.
