Abstract
Broadband hybrid 180 degrees and balun based on a parallel-strips transmission line are proposed. Two types of hybrids are presented: the first one is matched for VSWR = 2 from 0 to 11.5 GHz with amplitude error less than 0.06 dB and phase error lower than 0.5 degrees, but with low value of output ports isolation, and the second is matched for VSWR = 2 between 0 – 6 GHz with output amplitude error less thant 0.6 dB and phase error between 0 to 2 degrees and improved output ports isolation. The balun is based on the same structure, and is matched for VSWR = 1.4 between 0 – 11.5 GHz.
