Abstract

990,170. Impedance transforming couplings. TELEFUNKEN PATENTVERWERTUNGSG.m.b.H. Aug. 14, 1961[Aug. 16, 1960], No. 29259/61. Heading H1W. An impedance transformer comprises a number (three shown) of bifilar windings 6, 7, 8 . . . connected in series on the high impedance side to balanced terminals 1, 2 and connected in parallel on the low impedance side to a balanceto-unbalance transforming circuit. The latter comprises two equal lengths 11, 12 of co-axial line, the input being applied to the end of one of them and the corresponding end of the other being open-circuited. The inner conductors of the two lines are connected together whilst the outer conductors are connected to the inner conductors of a further pair of co-axial lines 17, 18 whose outer conductors form a balanced pair. These lines are open-circuited at the points where they join the input terminals of the transformer windings. The transformer and the balun are in two shielding boxes separated by a common partition 5.
