DESIGN AND DEVELOPMENT INVESTIGATIONS OF A LOW NOISE, LINEAR, VARIABLE GAIN, R. F. AMPLIFIER TUBE.
Abstract
In order to assess the requirements of the tubes for low interferences, an analysis was made of the power handling capability for cathode base, interbase and grid base circuitry. It was found that grid base operation should be applied only if the electronic loading is more important than the loading of 1/Gm. Based on the analysis, a figure of merit has been established which can be used for comparing different tube designs. Evaluation of construction A was continued, including life testing of tubes on high life line and measurement of shock, vibration, and fatigue in accordance with preliminary test specification. Dimensions of the electrodes of the tubes in construction D were determined, and lead inductance measurements for a 9-pin stem configuration were continued. The breadboard evaluation was completed, the R-390A receiver was modified and evaluated, and a comparison was made between tube types 6DC6 and WX4733.
