- IN STOCK - Please contact us if you need more units than what is available online.
Model SWT-28328-SA-381 is a WR-28 to 0.328” diameter circular waveguide mode transition. The mode transition is manufactured by either EDM machining or electro-forming techniques to ensure high accuracy and a quality surface finish. The transition only induces a fraction of a dB insertion loss and offers a return loss of 32 dB or better. The nominal operating frequency is 24 to 33 GHz. The dominate mode frequency range can be extended to cover 26.5 to 40 GHz if the higher order waveguide mode is not excited.
