Abstract
A tunable radio frequency (RF) duplexer and duplexing methods are disclosed. The tunable RF duplexer includes a first hybrid coupler, a second hybrid coupler, and an RF filter circuit. The first hybrid coupler is operable to split the RF transmission input signal into first and second RF quadrature hybrid transmission signals (QHTSs). The second hybrid coupler is operable to split the RF receive input signal into first and second RF quadrature hybrid receive signals (QHRSs). The RF filter circuit is operable to pass the first and second RF QHTSs to the second hybrid coupler and to reflect the first and second RF QHRSs back to the second hybrid coupler. Additionally, the second hybrid coupler is configured to combine the first and second RF QHTSs into an RF transmission output signal and to combine the first and second RF QHRSs into an RF receive output signal.
