摘要： This disclosure includes embodiments of a tunable hybrid coupler. The tunable hybrid coupler includes a first inductive element having a first inductance, a second inductive element having a second inductance and mutually coupled to the first inductive element, a first variable capacitive element having a first variable capacitance, and a second variable capacitance having a second variable capacitance. The first variable capacitive element is coupled between a first port and a second port. The second variable capacitive element is coupled between a third port and a fourth port. The first inductive element is coupled from the first port to the third port, while the second inductive element is coupled from the second port to the fourth port. Accordingly, the tunable hybrid coupler may form an impedance matching network that is tunable to different RF communication bands. The tunable hybrid coupler may thus be included in a tunable RF duplexer.

摘要： The present invention relates to a lumped cross-coupled Wilkinson circuit having a pair of magnetically cross-coupled inductive elements coupled to an isolation network. By magnetically cross-coupling the inductive elements, which have a mutual inductance, the inductance of each inductive element will be significantly less than the inductance of each inductive element in an equivalent lumped traditional Wilkinson combiner. Since the inductance of each inductive element is less, the size of each inductive element may be significantly smaller and the resistive loss of the each inductive element may be significantly smaller. In one embodiment of the present invention, the lumped cross-coupled Wilkinson circuit operates as a lumped cross-coupled Wilkinson combiner. In an alternate embodiment of the present invention, the lumped cross-coupled Wilkinson circuit operates as a lumped cross-coupled Wilkinson splitter.

摘要： A duplexer includes a common terminal, receiving filters, a transmitting filter, and a hybrid having four terminals (terminals 1 to 4). A first terminal (terminal 1), which is one of the four terminals of the hybrid is connected to the common terminal, the receiving filters are connected to a second terminal and a third terminal to which a signal is transmitted if it is input from the first terminal, and a transmitting filter is connected to a fourth terminal (terminal 4) of the hybrid. Thus, it is possible to improve the isolation of the duplexer, while avoiding an increase in the number of parts as well as greater complexity.
