Abstract :
Progress on the demonstration of a high power broadband three-beam Ka-band cascaded traveling-wave tube (TWT) prototype is presented. The amplifier will be driven by an electron gun (0.6 A × 3, 20 kV) adapted from our 18-beam multiple-beam klystron gun design. Both serpentine and folded-waveguide versions of the cascaded-TWT have been evaluated. The expected peak RF output power is 4.5 kW with 100 W of drive power at a frequency of 30 GHz. The minimum output power is 3 kW over a 5 GHz frequency band (4 kW over > 2 GHz).
