Waveguide Components

Richardson Electronics is a leading international manufacturer and provider of complete systems, standard components, and customized solutions for a variety of industrial applications utilizing continuous-wave (CW and pulsed) microwave technology. We design and manufacture high power RF and microwave components for use in CW and pulsed applications, covering the frequency range from 915 MHz to 5800 MHz and pulsed applications from 2998 MHz to 14500 MHz. Our primary customers are OEMs specializing in design and development of, plasma applications, industrial microwave heating systems, linear accelerators or ground, airborne or marine radar. We also offer hundreds of replacement parts in stock and ready for same-day shipping.

Circulator

Description | Circulators are three or four-port waveguide components utilizing ferrite technology to selectively direct energy to a specific port based upon the direction of wave propagation. By placing a load on the port where reflected energy is directed, a three-port circulator can be made into an isolator. R...

Isolator

Description | Isolators are three-port circulators which transmit microwave energy between ports, while directing reflected energy to a port with an attached load. In many industrial heating applications, the isolator is used to protect the magnetron from moding or over-heating caused by the reflected energy. Ric...

Waveguide

Description | Waveguide is required in a microwave system to efficiently transmit microwave energy from the source (generator) to the load (cavity/applicator). Waveguide can vary in shape, most commonly rectangular or circular, and waveguide size is dependent on the frequency and mode of propagation. Richardson E...

Waveguide Tuner

Description | Tuners are waveguide components used to match the load impedance with the source impedance. They minimize the amount of reflected power, providing the most efficient coupling of power to the load. Richardson Electronics supplies both manual 3- and 4-stub tuners, electrical and auto tuners. Auto and ...
