Traveling Wave Tube with Frequency Variable Sever Length, Abstract, In a traveling wave tube (TWT) with a non-dispersive interaction circuit such as a helix the, length of the circuit in wavelengths and hence the, gain of the tube, varies with the frequency. The variations of gain over a very wide bandwidth can cause oscillation problems. The The invention provides an inverse variation with frequency of the physical length over which the circuit interacts with the beam. This is done by resonant attenuators coupling to the interaction circuit over various lengths depending on their resonant frequency the, attenuation being enough to effectively remove the interaction circuit wave. The …

Why it's free to use
- Granted March 20, 1984. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended March 20, 2001.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
