Abstract
An elliptic combiner circuit filters a first and second signal in a first and second frequency band. A first resonator is coupled to a first input via a first capacitor and a second input via a second capacitor. A second resonator is coupled to a first and second signal path, coupled to the first and second input, via a third and a fourth capacitor. A first inductor is coupled between the first and third capacitors, and between the second and fourth capacitors. A third resonator is coupled to the first and second signal paths via a fifth, sixth, and seventh capacitors. A fourth resonator is coupled to the first signal path and a terminated port via an eighth, ninth and tenth capacitors. A second inductor is coupled between the fifth and eighth capacitors, and between the seventh and tenth capacitors. An output outputs the first and second signals.
