Planar Triode Construction: Planar Triode Construction - A short transit time is essential if grid loss and noise are to be minimized, as is the reduction of internal capacitances and…
Resonators and Waveguides Articles: Rectangular Waveguides: As we know already that the term skin effect indicated that the majority of the current flow (at very high frequencies) will occur mostly…
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 Mixers and Detectors: As we know that ordinary transistor and tube RF amplifiers eventually fail at microwave frequencies, because of greatly increased noise, compared with their low-frequency performance. Unless…
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…
Directional Coupler Waveguide: We already know that a transmission-line Directional Coupler Waveguide. Its applications were indicated at the time as being unidirectional power flow measurement, SWR measurement and unidirectional wave…
Cavity Resonators: A cavity resonators is a piece of waveguide closed off at both ends with metallic planes. Where propagation in the longitudinal direction took place in the waveguide, standing…
Waveguide Junctions: When it is required to combine two or more signals (or split a signal into two or more parts) in a waveguide system, some form of multiple junction…
