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 Electronics supports 915/922/896MHz, 2450MHz, 5.8GHz as well as other ISM frequency bands. Waveguide can be supplied as straight sections, bends, twists, flexible and transitions pieces. We also offer customized waveguide per your requirements.
