AuthorShyam, Megha (K. S. Meghashyam)
Biographical NotesMegha Shyam (also known as K. S. Meghashyam) was born in India. He attended the University College of Engineering of Osmania University, India (Electrical Engineering 1956–1960) and the Indian Institute of Science in Bangalore (Electrical Communication Engineering 1960–1961). In the U.S. he attended Harvard University (Applied Physics 1961–1963) and Stanford University (Electrical Engineering 1963–1966). He joined Fairchild circa 1966 where in 1968 he worked on compound semiconductor device technology in the New Phenomena section reporting to (later Nobel Prize winner) Herbert Kroemer. Subsequent employment included R&D Manager at Bell and Howell (1970–1972); Reliability Manager at American Microsystems Inc. (1972–1974); Member of Technical Staff at Data General (1974–1975); Reliability Manager at Synertek (1975–1977); Technical Staff at Hewlett-Packard (1977–1990); Sparcom Corporation co-founder (1990–1996); and da Vinci Technologies, Owner (1996–2002).

DescriptionThis volume records the results of FM noise measurements on Gunn Effect diode oscillators supplied by the Fairchild Microwave Products division. Entries include a photo of the waveguide mechanical design (p. 31); numerous tables of laboratory measurements and hand-drawn and recorder-plotted graphs; and copy of a handwritten specification of a desired Five Point voltage measurement system (p.137). Appears to cover 1968-10-02-1970-04-01 but pages are not always filled out in chronological order.
