Abstract : The design of the four-element crystal protector, the two-element preTR, and efforts in the design of the solid-state varactor limiter were completed. In addition, the packaging of the preTR and crystal protector was completed. A series of life tests were conducted on the gas discharge devices, establishing the inadequacy of a single fill gas TR tube, and the merits of a dual fill combination. From these tests, the need of a gas reservoir was shown. In place of the limiter effort, which was terminated, the merits of an externally biased PIN switch will be investigated. Such a device, when added to the gas tube, is expected to substantially improve the crystal protection reliability. (Author)
