Abstract
A system and method for leak suppression in a full duplex system is disclosed. In an embodiment, a system for wireless transmission and reception includes a circulator having a common port, an input port and an output port; a conjugate matching tuner coupled to the common port; and an antenna coupled to the conjugate matching tuner, an impedance of the antenna being conjugate matched to an impedance of the common port of the circulator by the conjugate matching tuner.
Claims19
A system for wireless transmission and reception, comprising:
- a circulator having a common port, an input port and an output port;
- a conjugate matching tuner coupled to the common port;
- and
- an antenna coupled to the conjugate matching tuner, an impedance of the antenna being conjugate matched to an impedance of the common port of the circulator by the conjugate matching tuner.
A network component, comprising:
- a circulator comprising an input port, a output port, and a common port;
- a transmitter connected to the input port of the circulator;
- a voltage standing wave ratio (VSWR) tuner comprising a first port and a second port, the first port connected to the common port of the circulator;
- a receiver connected to the output port of the circulator;
- and
- an antenna connected to the second port of the VSWR tuner,
- wherein the VSWR tuner substantially minimizes a leak of a transmission signal into the receiver.
A method for manufacturing a full duplex system;
- the method comprising:
- connecting a first port of a conjugate matching tuner to a common port of a circulator;
- and
- connecting a second port of the conjugate matching tuner to an antenna, an impedance of the antenna being conjugate matched to an impedance of the common port of the circulator by the conjugate matching tuner.
A method for transmitting and receiving a signal in a full duplex wireless device, the method comprising:
- transmitting a transmitted signal to an input port of a circulator having a common port, the input port and an output port;
- and
- conjugately matching an impedance of the common port of the circulator with an impedance of an antenna thereby reducing reflection of the transmitted signal appearing at the output port of the circulator.
