.~ With coupling network or impedance in the leadin {9}
859
.~.~ Balanced to unbalanced circuit
DEFINITION
Classification: 343/859
(under subclass 850) Subject matter wherein the passive coupling network includes four terminals, one pair of which are for connection to the antenna and the other pair for connection to a source or receiver of signal energy; the network impedance across one pair of terminals being symmetrical and the network impedance across the other pair of terminals being unsymmetrical with respect to a given potential plane (e.g., ground), these impedances being effective to convert symmetrical potential applied at the symmetrical pair of terminals to unsymmetrical potential at the other pair of terminals or vice versa.
