Abstract
A wide-band phase shifter rectangular in cross section with transverse corrugations on all four walls is presented in this letter. The loadi ng for the two orthogonal modes is different and is achieved by choosi ng dissimilar corrugation parameters. This phase shifter measures a re turn loss of -25 dB or better and differential phase shift of 90 degre es +/- 3.3 degrees between 18.9-26.5 GHz. This all-metal robust phase shifter is ideal for cryogenically cooled radio astronomy receivers.
