UHF SMALL SIGNAL TRANSISTOR.

The report covers principally the design, fabrication, and electrical evaluation of the final quantity of transistors made under this contract. The final shipment of transistors consists of 30 transistors in the stripline package and 70 transistors in a modified TO-18 package. A detailed analysis of all experimental data is given. All transistors meet or exceed the primary requirements on power gain, stability, and noise figure. This includes a gain figure greater than or equal to 37 db unilaeral gain greater than or equal 12 db stability factor between 0.7 - 1.5 and noise figure less than 6 db at 500 Mc at the operating level of 12 mW. Reliability data on units mounted in the stripline package is furnished a further report will cover environmental tests on the modified TO-18 package. Author
