Abstract

1,146,032. Valve amplifying circuits. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 25 March, 1966 [26 March, 1965], No. 13246/66. Heading H3W. [Also in Division H1] An aperiodic high frequency amplifier is provided with negative feedback by means of a pair of capacitors 6, 7, Fig. 1, which include, and may comprise only the valve capacitances, connected in series across the output and with the grid connected to their common point. Capacitors 6, 7 form, together with a pair of inductors 8, 9 also connected in series across the output, a balanced bridge network, points a, b being at the same potential. Inductor 9 comprises the outer of a length of coaxial cable, the inner conductor of which is connected to point a to supply signal to the grid; the output signal does not appear on this conductor, owing to the balanced nature of the bridge network. A screened resistor may be connected between points (a, b), (Fig. 2, not shown), to terminate the cable, and where the latter is short and may be regarded as lumped capacitance it may be built out with series inductance at both ends: inductance may likewise be added between the point (a) and the cable end corresponding to compensate for the capacitance 7. In a pushpull modification, Fig. 3, a transformer is used, the centre-tapped main winding 18 of which is connected between the valve anodes, while the grids are fed over two auxiliary windings 17, 17<SP>1</SP> each of which comprises a length of concentric cable.
