Julius Lange


  • 1980, Microwave Application Award, Past Awardees**


Julius Lange received his B.S. degree in Engineering Physics and his M.S. degree in Physics from
the University of Oklahoma in 1959 and 1960, respectively. He received his Ph.D. in Electrical
Engineering from Southern Methodist University in 1971.
In October 1979 Dr. Lange joined the Mobile Communications Business Division of the General
Electric Company as Consulting Engineer. He is presently working on the AMPS cellular mobile
telephone system.
From 1973 to 1979, Dr. Lange was associated with the Western Laboratories Division of Ford
Aerospace Corporation as Senior Engineering Specialist in circuit design and system analysis. His
assignments included: digital satellite communications receivers for rates up to 1000 Megabits per
second, an adoptive baseband equalizer, and computer aided design of GSAS FET amplifiers.
From 1971 to 1973, Dr. Lange joined the Advanced Development Department of the Radar Systems
Division of Texas Instruments where he worked on varactor multipliers and parametric amplifiers. From
February to October 1971, Dr. Lange was employed at Collins Radio as senior engineer in the Solid
State Power Amplifier Advanced Development Group of the Telecommunications Systems Engineering
From 1965 to 1970 he was associated with Texas Instruments Incorporated as a senior member of
the technical staff of the Microwave Components Program Branch of the Semiconductor Research and
DevelopmentLaboratorywhere he has had responsibility for the design and performance evaluation of
microwave transistors and circuits. His assignments included: improved device analysis techniques
involving correlation between physical structure and high frequency parameters; package and test fixture
design; noise and S-parameters measurement techniques; computer aided device characterization;
computer aided design of microwave wideband amplifiers, directional couplers and filters; design of
microwave integrated circuits on ceramic substrates; and package design.
Between August 1960 and June 1965, Dr. Lange was employed with the Semiconductor Device
Development Department of Bell Telephone Laboratories, where he worked on: fabrication of gallium
arsenide transistors; Hail and resistivity measurements on thin films; radiation testing of transistors;
design and testing of nanosecond switching circuits; and microwave transistor characterization.
Dr. Lange is a graduate of the “Communications Development Training Program” of Bell Telphone
Laboratories, and of the “Modern Business Program” of the Alexander Hamilton Institute. He has
published papers in the Journal of Applied Physics, and IEEE Journal of Solid-State Circuits, the IEEE
Transactions on Circuit Theory, and IEEE Transactions on Microwave Theory and Techniques, and the
IEEE Transactions on Electron Devices.
Dr. Lange has held the office of publicity chairman for the 1969 International Microwave Symposium
and the office of program chairman for the Dallas GMIT chapter.
He is married and has an eight year old daughter.
