VARACTOR DIODE INDUSTRIAL PREPAREDNESS MEASURES.

Abstract

Efforts continued on a program to mass-produce a microwave silicon diffused mesa varactor diode. Work was performed to determine the dependence of series resistance on measurement frequency. Glass varactor diodes were tested for series resistance at both 500 Mc and 1120 Mc. The series resistance measurement consists of shunting a transmission line with a varactor, and it was adopted because of its convenience and reproducibility. At low measurement frequencies circuit losses become important and there is evidence that indicates that series resistance should be measured in the vicinity of 1 to 2 Gc to obtain satisfactory results. A new welded varactor package style is also discussed. This varactor package has allowed the use of a bonded contact, open type construction for ease of fabrication, and welded final seal which has provided for a more reliable finished semiconductor product.
