The Traveling-Wave Tube (TWT) is a high-gain, low-noise, wide-bandwidth microwave amplifier. It is capable of gains greater than 40 dB with bandwidths exceeding an octave. (A bandwidth of 1 octave is ...

Sheet beam traveling‐wave tubes (TWTs) represent a sophisticated class of vacuum electronic devices that employ a broad, thin electron beam to interact coherently with radio frequency waves along a ...
