摘要：
A high frequency folded waveguide travelling wave tube (TWT) has been designed to test this delay line technology. Envisaged applications of the technology are in satellite communications. PIC simulations predict an output power similar to 100 W over the frequency range of 71 - 76 GHz can be achieved for an input power of similar to 9 mW (40dB gain) using such a folded waveguide. Simulations of the return loss of the vacuum windows yield values lower than -30 dB cross the frequency band of interest.
