An analysis is made of two life tests conducted during the quarter on combination pre TR-crystal protector TR tubes. The results indicate that the keep alive is the limiting factor of operational life expectancy. Additional work on two and three element pre TR tubes is summarized, and the advantages and drawbacks of the two possible approaches are shown. The problem of high insertion loss of present PIN switches is presented. Methods of improving this loss - in view of the lower isolation needed in a gas-solid state combination device are discussed. A preliminary life test on such a device shows promising results. Author
