<p>An anti-reciprocal network, comprising at least a first and a second port each with two terminals, which ports are included in a closed loop which moreover comprises at least three impedance elements, whilst the network also comprises two amplifiers which are coupled to the two ports, characterized in that each of the amplifiers is constituted by a transistor, whilst the closed loop, in this order, is formed by the first terminal of the first port, a first impedance element, a second impedance element, a first and the second terminal of the second port, a third impedance element, and a second terminal of the first port, the base-collector path of a first transistor being included between the second terminal of the second port and the first terminal of the first port and the collector-emitter path of a second transistor being included between the first terminal of the second port and the second terminal of the first port, whilst the base of said second transistor is connected to the terminal of the first impedance which is remote from the first terminal of said first port.</p> |
