Abstract

515,864. Valve circuits. WHITE, E. L. C. June 30, 1938, No. 19442. [Classes 40 (iii) and 40 (v)] The circuit of an ultra short wave thermionic amplifier consists of three coaxial tubular conductors 5, 6, 8. Conductor 6 is earthed and connected to the grid 2 of the valve, conductor 5 being connected to the anode 1 and the high tension supply, while flanges at the lower ends of conductors 5, 6 form a condenser with insulation 7. A metal tube 8 is connected to the cathode 3 via blocking condensers 9 at one end and is effectively earthed to the rim of conductor 6 at the other end. Heater current for the valve is supplied through conductors 10 from a source 11 and a source 12 provides grid bias. The input radio frequency oscillations are fed into the amplifier by conductor 13 suitably tapped on the cathode circuit and the output is taken from a tapping on the outside of tube 6 and is conveyed by lead 14 to the load 15. The input circuit, due to the manner of its connection to the cathode, is heavily damped but the power absorbed in this imput impedance is not dissipated but is transferred to the anode circuit. As the outside of tube 5 and the anode are effectively at earth radio frequency no'loss is introduced by the water jacket 16 or any cooling fins attached to the anode. If desired the tube 5 may be connected to earth and the cathode maintained at a suitable negative potential, the grid being suitably biased and earthed through a condenser or acceptor circuit.
