摘要： Multi-port hybrid-based cancellation networks may be used to enable simultaneous transmit and receive in one or more co-existent communication systems. A multi-port hybrid-based cancellation network may include a first and second quadrature hybrid, a first and second two-port network, and other circuitry components. The second quadrature hybrid may be distinct from the first quadrature hybrid. The first two-port network may include a first filter or a first amplifier connected between the first and the second quadrature hybrids. The second two-port network may include a second filter or a second amplifier that is distinct from but essentially the same as the first filter or the first amplifier connected between the first and the second quadrature hybrids.

摘要： A multi-port hybrid-based cancellation network may include a first and second hybrid coupler, and a first and second two-port network. The second hybrid coupler may be distinct from the first hybrid coupler. The first two-port network may include a first filter connected between the first and the second hybrid couplers. The second two- port network may include a second filter that is distinct from but essentially the same as the first filter connected between the first and the second hybrid couplers. Other circuitry components may be connected to one of the ports of multi-port hybrid-based cancellation network. These other circuitry components may have a configuration that increases or maximizes signal isolation between at least two of the ports of the multi-port hybrid-based cancellation network.

摘要： A two-port tunable or reconfigurable network having a filter transfer function may include: a network input port; a network output port; a hybrid coupler having a hybrid input port, a hybrid isolated port, a hybrid through port, and a hybrid coupled port; a first internal two-port network connected between the network input port and the hybrid input port; a second internal two-port network connected between the network output port and the hybrid isolated port; and a third internal two-port network connected between the hybrid through port and the hybrid coupled port. At least one of the first internal two-port network, the second internal two-port network, the third internal two-port network, and the hybrid coupler may be tunable or reconfigurable in response to an electrical signal or a user-operated control in a way that tunes or reconfigures the filter transfer function of the two-port tunable or reconfigurable network.

摘要： A passive cancellation network may include a transmit input having a configuration that passively receives a transmit signal from a transmitter that is to be wirelessly transmitted; a transmit output having a configuration that passively delivers the transmit signal after processing by the passive cancellation network; a receive input having a configuration that passively receives a receive signal that includes undesirable leakage from the transmit signal; a receive output having a configuration that passively delivers the receive signal after processing by the passive cancellation network; and a passive feed forward cancellation circuit that passively cancels at least a portion of the undesired leakage from the transmit signal in the receive signal in a feed forward manner.
