Abstract
635,830. Aerial coupling arrangements. PHILIPS LAMPS, Ltd. Nov. 26, 1946, No. 35077. Convention date, May 29. 1943. [Class 40 (v)] [Also in Group XL (b)] Two transmitters 2, 3, similarly modulated, are coupled to a common load 1 by a bridge which has in each arm an impedance inverting # network 5, 6, 7, 8. The phase shift between output current and input voltage occurring in network 8 is the opposite of that in the other networks. A balancing impedance 9 is connected to the remaining corner of the bridge. The circuit prevents interaction between the transmitters.
