Abstract

The amplifier system has several coaxial circuits, such as cathode circuit, screen grid circuit, anode circuit with a waveguide and terminating resistor and a secondary circuit esp. with coaxial tetrodes and triodes in coaxial tank circuits of t.v. power amplifiers. At least three waveguides (17) are provided in the H.F. amplifier anode circuit, coupled through a resonance iris (18) to the tank circuit parasitic wave, and a non-reflecting absorber (19) is provided in the waveguide for the parasitic wave, in the form of a dielectric substance distributed in the waveguide.
