Abstract

By the use of a direct-current feedback network which minimizes variations in plate current, the output of a radiofrequency amplifier can be made to be independent of heater-voltage fluctuations. Under- or over-compensation may be obtained by choice of circuit components to meet individual requirements. The design procedure for this network is indicated, and the experimental results for a compensated 30-mc broad-band intermediate-frequency amplifler are shown.
