A broadband TEM mode four-port hybrid in a single-level microwave circuit in a transmission line medium selected from among the stripline, microstrip, airstrip, etc. media. The device employs coupled strip all-pass filter elements to provide a hybrid wherein isolation to the cross ports, power division to the coupled ports, and the 0 DEG and 180 DEG output phase relationships are independent of frequency over substantial frequency bandwidths. |
