Abstract
959,078. R.F. couplings. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Oct. 5, 1962 [Oct. 5, 1961], No. 37688/62. Heading H4A. In a bridge circuit 1, 2, 3, 4 between two H.F. sources (e.g. radio transmitters), a load RV (e.g. an aerial) and a load-balancing resistor RLA, switches S1 S2 are provided at respective mid-points of sections 1, 3 and 2, 4 whereby at will either both sources feed only the load RV or one source feeds only load RV and the other source feeds only resistor RLA; and it is arranged that in the first case that the H.F. outputs at load RV are in phase by feeding energy in phase quadrature from the sources at terminals 1, 3. In the first embodiment the bridge sections are quarter-wavelength coaxial feeders of the denoted characteristic impedances ; or the bridge sections may each be of length (2n-1)#/4 where n is any positive integer and # is the mean operating wavelength. In further embodiments: (1) the sections 1, 3 and 2, 4 are lumped capacitative reactances, Fig. 2 (not shown), or lumped inductive reactances, Fig. 3 (not shown); (2) all the bridge sections are lumped inductive reactances. Fig. 4 (not shown); (3) Lecher lines are utilized.
