Traveling Wave Tube Working

Traveling Wave Tube Working(TWT): Like the multicavity klystron, the Traveling Wave Tube Working is a linear-beam tube used as a microwave amplifier. Unlike the klystron, however, it is a device…

Waveguide Switch Design

Waveguide Switch Design: It is often necessary to prevent microwave power from following a particular path, or to force it to follow another path; as at lower frequencies, the component…

Waveguide Isolator and Circulators

Waveguide Isolator and Circulators: It often happens at microwave frequencies that coupling must be strictly a one-way affair. This applies for most microwave generators, whose output amplitude and frequency could…
