We present a waveguide system which makes it possible to input/output radiation to and from a low-magnetic-field-operating W-band gyro-TWT being currently under development. The system makes it possible to use one barrier window at the collector's end both for radiation inputting and outputting.
This paper presents the experimental study of microwave pulse compression using a five-fold helically corrugated waveguide. In the experiment, the maximum power compression ratio of 25.2 was achieved by compressing an input microwave pulse of 80-ns duration and 9.65–9.05-GHz frequency swept range into a 1.6-ns Gaussian-envelope pulse. For an average input power of 5.8 kW generated by a conventional...
