Abstract: A power circuit suitable for combining or splitting broadband signals. The circuit includes a stepped impedance section, a core section and a first, second and third port. The stepped impedance section and the core section are interconnected at an interconnection. The stepped impedance section includes a first transmission line running from the first port to the interconnection. The core section includes a second and a third transmission line running from the interconnection to the second and third ports, respectively. The second and third transmission lines each have at least a first and a second core subsection. The number of core subsections of the second transmission line and the number of core subsections of the third transmission line is equal, to the number of stepped impedance subsections of the stepped impedance section.

Abstract: The filter unit has a center frequency and comprises a first dielectric substrate, a first conducting plane, and at least one transmission arrangement. The at least one transmission arrangement comprises a shunt node which has a shunt connection to the conducting plane. The electrical length of the shunt connection defines the center frequency of the filter unit. The transmission arrangement further comprises a plurality of transmission lines connected in series between an input port and an output port, wherein each port is connectable to auxiliary systems with a system impedance. Moreover, each transmission line has a characteristic impedance and wherein the characteristic impedance of each transmission line is less than the system impedance.
