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.

Abstract: In one embodiment, a balanced to unbalanced transformer utilizes a crossover configuration such that some portion of the secondary coil (inductor) is shared between two resonators (capacitors). Adding a first capacitor in parallel with a portion of the secondary inductor creates a first harmonic trap (filter), and also efficiently uses the secondary coil (inductor) as a resonating element.Adding a second capacitor which shares (crossover configuration) a portion of the secondary inductor with the first capacitor creates a second harmonic trap (filter), which may be tuned to the same harmonic as the first harmonic trap, or may be tuned to a different harmonic.
