Abstract:

Four 1 kW pulsed traveling wave tubes were combined in parallel to produce greater than 4 kW over the IJ band octave from 8.0 to 16.0 GHz. Combining loss due to phase and amplitude imbalance in the TWTs was found to average 0.2 dB. Combining loss attributable to insertion loss and VSWR amounted to 0.5 dB per output combining magic tee. Double-ridge waveguide magic tees and TWTs were evaluated for extended frequency operation and higher output power as a function of frequency while varying cathode voltage, grid drive voltage, input rf drive level, and duty cycle.
