Abstract (en)
[origin: EP0321331A1] Power coupling device which can be used with metre and decimetre waves. In order to share out to n users (E1-En) in an equipotential and equiphase manner the energy coming from m equipotential and equiphase sources (J1-Jm), at the output of each source is connected up a 3dB, 90 DEG hybrid circuit (H1-Hm) which distributes the power equally and with an aperiodic phase shift of 90 DEG to two equipotential and equiphase distribution boxes (G1-G2) with m inputs and n outputs, exhibiting the same input/output phase shift. The two boxes are connected respectively to the two pathways of a pair of conjugate pathways of n 3dB, 90 DEG hybrid circuits (F1-Fn); the recombined powers in these n circuits are delivered respectively to the n users (E1-En). Application in particular to power transmitters. <IMAGE>
