Abstract:
This disclosure relates to hybrid couplers for radio frequency (RF) signals. The hybrid coupler includes a first port, a second port, a third port, a fourth port, a first inductive element connected from the first port to the third port, and a second inductive element connected from the second port to the fourth port. The hybrid coupler further includes a first capacitive element and a second capacitive element. The first capacitive element is connected between an intermediary node of the first inductive element and either the first port or the third port, while the second capacitive element is coupled between an intermediary node of the second inductive element and either the second port or the fourth port. Accordingly, the first capacitive element and a portion of the first inductive element and the second capacitive element and a portion of the second capacitive element each form a harmonic trap.
