Electrical specifications of the PEM device type L-148 have been incorporated into the Electronics Command Technical requirements SCL-7730B. They are included in this report. Final approval of the specifications have not yet been announced by USAEC. Forty preproduction samples fabricated during the report period have been tested according to Specification for Transistor, Microwave, Germanium 1.5 GHz, 3.0 GHz Type L-148. Electrical data on these samples are enclosed. During this report period, a technical problem encountered was caused by defective slice resistivity measuring apparatus. The problem has been corrected and acceptable substrate material is being received. The L-148 pattern is now being used exclusively on the preproduction line. Progress is being made toward realizing the full capability of PEM facilities. A revised list of PEM electrical and environmental test equipment is enclosed. Author
