A broadband 180 degree hybrid having lumped or semi-lumped elements is comprised of a network of low and high pass filters. A 180 degree phase differential is obtained by splitting an input signal from a first input. A first portion of the split signal is passed through a low pass filter and a second portion is passed through a high pass filter. The phase differential is maintained at 180 degrees. A zero (0) degree phase differential is obtained by splitting an input signal from a second input and passing both portions through a pair of low pass filters or through a pair of high pass filters.
