Abstract
This utility model relates to a broadband high-power combining circuit and a combiner, comprising: a impedance-reducing sub-circuit and an impedance-raising sub-circuit; the output terminal of the impedance-reducing sub-circuit is connected to the input terminal of the impedance-raising sub-circuit; the input terminal of the impedance-reducing sub-circuit is configured as the input terminal of the broadband high-power combining circuit, and the output terminal of the impedance-raising sub-circuit is configured as the output terminal of the broadband high-power combining circuit; the impedance-reducing sub-circuit and the impedance-raising sub-circuit include a coaxial magnetic ring transformer, which is formed by passing a coaxial line through a magnetic ring to form a transformer, with the inner conductor of the coaxial line serving as the primary coil of the transformer and the outer conductor serving as the secondary coil of the transformer; in the impedance-reducing sub-circuit, the coaxial line of the coaxial magnetic ring transformer is stranded in the magnetic ring; in the impedance-raising sub-circuit, the coaxial line of the coaxial magnetic ring transformer is arranged parallel to and passes through the magnetic ring.
