Abstract
A coupler including: a first conductive line intended to convey a signal to be transmitted between first and second terminals; a second conductive line, coupled to the first one and having one end intended to provide, on a third terminal, data relative to a signal reflected on the second terminal; and an inductive and/or capacitive impedance matching circuit, interposed between the other end of the second line and a fourth terminal of the coupler.
Claims24
A coupler comprising:
- a first conductive line intended to convey a signal to be transmitted between first and second terminals;
- a second conductive line, coupled to the first one and having one end intended to provide, on a third terminal, data relative to a signal reflected on the second terminal;
- and
- an inductive and/or capacitive impedance matching circuit with no resistive element, other than a circuit exclusively used for the decoupling of a D.C. voltage, interposed between the other end of the second line and a fourth terminal of the coupler, the inductive and/or capacitive impedance matching circuit being adapted to generate a reflected signal.

A coupler, comprising:
- a first conductive line;
- a second conductive line coupled to the first conductive line;
- and
- an inductive and/or capacitive element coupled to a terminal of the second conductive line and having an impedance configured to generate a reflected signal that reduces a parasitic signal from a terminal of the first conductive line.
1 more element
A coupler, comprising:
- a first conductive line;
- a second conductive line coupled to the first conductive line;
- and
