Abstract
1386339 RF couplings NAUTICAL ELECTRONICS LABORATORIES Ltd 13 Oct 1972 1972 [2 Nov 1971] 47456/72 Heading H4A A combiner network for two synchronous sources comprises a single transformer having first and second windings one end of each of which is connected to a respective input port, and the other ends of which are connected to an output port. The windings are connected with mutually opposing directions of current flow, and under rated operating conditions the net flux in the transformer core is zero. Dissipative means is coupled across at least one of the windings, and is operative if there is a departure from the zero flux condition. As shown in Fig. 3 the feed sources are connected to respective input ports 18, 19 and a load R L is connected to an output port 21. The dissipative means is a resistor R D which is connected across one winding 32 of the transformer 30. In another embodiment a resistor is connected across a tertiary winding of the transformer (Fig. 2, not shown). In a third embodiment, dissipation is provided by using a material with high losses for the transformer core.
