This experimental work has been directed towards the design and development investigations of a low noise, linear, variable gain, RF amplifier tube with improved linear dynamic range signal handling capacity for the purpose of reducing cross modulation, intermodulation and overload. During this quarter improvement of the noise level of the tubes without destroying the good level of interference suppression was attempted. Tests were made to find a simple automatic gain control system which could be incorporated in the design. The dimensions of construction D in so far as the dimensions have influence on the transfer characteristics are defined. Tests were performed on the R390A receiver to establish the receiver characteristics for a comparative evaluation.
