C-BAND AND X-BAND DUAL-FUNCTION OSCILLATORS.
Abstract
A sufficient number of tubes of the two-layer etched frame grid design were made for life testing and retubing. One lot of tubes having the interlaced damper wire grid structure has been made. Increased Gm and attendant alteration of feedback phase necessitated reoptimizing the C-band oscillator. Reoptimization resulted in the deletion of the phasing line within the grid sleeve of the oscillator. The modified oscillator is called Oscillator DC-57. The C-Band oscillators for life tests and final evaluation were assembled and initial data recorded. The performance from unit to unit is remarkably uniform. Tests were initiated to determine the reason for the unexpectedly poor performance of the laminated etched grid frame design tubes at X-Band frequencies. Computer results confirm the experimental results. Results of computer analysis do indicate, however, that if the interelectrode spacings were changed, and then if the appropriate voltages were applied in a circuit with the proper feedback phase and magnitude, that a peak power of 63 watts to 76 watts could be expected.
