Development of Ku-Band Low-Noise Dual Output Function Traveling-Wave Tubes

摘要

Preliminary studies have shown that the helix design of present MEC Ku-band tubes are not centered for maximum performance in the 12 to 18 Gc band. Therefore a design change has been made to correct the situation. Magnetic-field and package-weight considerations have dictated an Alnico V magnet for the PM portion of the PM-PPM focusing array.
