    Abstract: This disclosure relates generally to directional couplers. In one embodiment, a directional coupler includes a first port, a second port, a third port, a first inductive element, a second inductive element, a first switchable path, and a second switchable path. The first inductive element is coupled between the first port and the second port, while the second inductive element is mutually coupled to the first inductive element. The first switchable path is configured to be opened and closed, wherein the first switchable path is coupled between a first location of the second inductive element and the third port. The second switchable path is configured to be opened and closed, wherein the second switchable path is coupled between a second location of the second inductive element and the third port. In this manner, a directivity of the directional coupler can be switched between a forward direction and a reverse direction.

    Abstract: RF duplexing and methods of operating the same are described herein. In one embodiment, an RF duplexing system may include a control circuit and a duplexer with a first tunable RF filter and second tunable RF filter. The control circuit is operable in a full duplexing transmission mode and a half duplexing transmission mode. The control circuit tunes the first tunable RF filter in the full duplexing transmission mode so that the first tunable RF filter defines a transmission passband and tune the second tunable RF filter so that the second tunable RF filter defines a receive passband. Also, the control circuit tunes one of the tunable RF filters so that the tunable RF filter defines the passband while the other tunable RF filter enhances the passband. In this manner, the tunable RF filters in the duplexer are both utilized to get better performance during the half duplexing mode.

    Abstract translation: RF双工及其操作方法在此描述。 在一个实施例中，RF双工系统可以包括具有第一可调谐RF滤波器和第二可调谐RF滤波器的控制电路和双工器。 控制电路可在全双工传输模式和半双工传输模式下工作。 控制电路以全双工传输模式调谐第一可调谐RF滤波器，使得第一可调谐RF滤波器定义传输通带并调谐第二可调谐RF滤波器，使得第二可调谐RF滤波器限定接收通带。 此外，控制电路调谐一个可调谐RF滤波器，使得可调谐RF滤波器限定通带，而另一个可调谐RF滤波器增强通带。 以这种方式，双工器中的可调谐RF滤波器都用于在半双工模式期间获得更好的性能。
