Abstract
Embodiments of a tunable radio frequency (RF) diplexer and methods of duplexing transmission and receive signals are disclosed. In one embodiment, the RF diplexer includes a first hybrid coupler, a second hybrid coupler, and an RF filter circuit, and a phase inversion component. Both the RF filter circuit and the phase inversion component are connected between the first hybrid coupler and the second hybrid coupler. In some embodiments, the phase inversion component is provided by the RF filter circuit, while in other embodiments, the phase inversion component is provided separately. The phase inversion component is configured to provide a differential phase shift. The benefit of introducing the differential phase shift is that it provides increased isolation and broadband isolation between the different frequency bands being diplexed by the RF diplexer.
