1. A power combiner comprising:
- a primary winding and a secondary winding, wherein at least the primary winding comprises a center-tap; and
a termination module operably coupled to the center-tapped primary winding and arranged to provide harmonic terminations on a plurality of frequencies;
wherein at least one of the primary winding and the secondary winding is operably coupled to an amplifier stage via a power combiner circuit having a plurality of input terminals and a plurality of output terminals, such that each input of the input terminals is coupled to a corresponding same output terminal;
the plurality of input terminals comprise different pairs of a plurality of first paired input terminals and a first pair of cross coupled bond wires of the power combiner circuit operably couples a pair of the plurality of input terminals with a different input terminal via terminals of different pairs of the plurality of first paired input terminals; and
a second pair of cross coupled bond wires of the power combiner circuit overlays the first pair of cross coupled bond wires.
