Abstract
A non-reciprocal bidirectional duplexer includes a first transmission medium extending from a first terminal to a third terminal; a second transmission medium extending from the second terminal to the third terminal; and a plurality of non-reciprocal, bidirectional phase shifting elements, coupling the transmission mediums and spaced along them; each of the phase shifting elements includes means for amplifying a signal in a first direction from the first to the second transmission medium and for amplifying a signal in the second direction from the second to the first transmission medium; and means for establishing a phase differential between the signals moving in the first and second directions.

A non-reciprocal, bidirectional duplexer comprising:
- a first transmission medium extending from a first terminal to a third terminal;
- a second transmission medium extending from a second terminal to said third terminal;
- and
- a plurality of non-reciprocal, bidirectional phase shifting elements coupling said transmission mediums and spaced along them;
- each said phase shifting element including means for amplifying a signal in a first direction from said first to said second transmission medium, and for amplifying a signal in a second direction from said second to said first transmission medium, and means for establishing a phase differential between the signals moving in said first and second directions.
A non-reciprocal, bidirectional circulator comprising:
- a first transmission medium extending from a transmitter terminal to an antenna terminal;
- a second transmission medium extending from a receiver terminal to the antenna terminal;
- and
- a plurality of non-reciprocal, bidirectional phase shifting elements coupling the transmission mediums and spaced along them;
- each said phase shifting element including means for amplifying a signal in a first direction from the first to the second transmission medium, and for amplifying a signal in a second direction from said second to said first transmission medium, and means for establishing a phase differential between the signals moving in said first and second directions.
