C-BAND AND X-BAND DUAL FUNCTION OSCILLATORS.
Abstract
Effort is continuing toward the design of a grid structure that will reduce to an acceptable level the FM component of the RF output attributable to grid wire motion. Several lots of tubes were made with widely dispersed characteristics in order to determine the optimum design for operation as a dual function oscillator. Two slot-coupled CW reference oscillators were made and found to be satisfactory. It was found that an oscillator cavity, optimized for the 7910 tube type, was not optimum for the Y-1662 tube type. It will, therefore, be necessary to postpone finalization of the internal structure of the oscillator until the final tube design has been made. A change of 86 MHz in the frequencies difference between the frequency of the transmit function and that of the local oscillator function was realized by an alteration of the internal impedance ratio of the oscillator.
