This article was originally fully published in Microwave & RF in August of 2006. Here we reprise an abridged version of ten engineers and companies listed. Including KRYTAR founder Thomas J. Russell.

Through innovation and invention, the following people, have all shaped the microwave industry.

  1. BILL HEWLETT and DAVE PACKARD – In 1938, these friends and Stanford University alumnae set up their first workspace in a garage in Palo Alto, CA. Their ini­tial capital was reportedly $538, They created the first Hewlett-Packard prod­uct—a resistance-capacitance audio oscillator. The HP Model 200A was used to test sound equipment. Sixty years later, they had a $25-billion com­pany that was central to propelling technology forward (and would spin off their test and measurement business as a separate public company, Agilent Technologies). Aside from technology innovation, these famous founders are known for the work atmosphere that they created, dubbed “The HP Way.”
  2. BARRIE GILBERT – This circuit designer, who holds more than 60 patents, created the Translinear Principle that is used in so many of today’s ICs. He also is cred­ited with uniting waveform sampling techniques and real­time oscillography in one instrument.Modern communi­cations largely rely on his Gilbert cell, which is used as a mixer and frequency translator. Gilbert, an Analog Devices Fellow, started ADI’s Northwest Labs design center in Ore­gon. There, he continues to work on RF products crafted with high-speed non­linear circuit techniques.
  3. JAMES CLERK MAXWELL – The “father of modern physics,” as he is often called, discovered the theory of electromag­netism, His equations, which were proven correct by Heinrich Hertz, are at the root of computational electro­magnetics. Maxwell put forth the idea that energies reside in fields as well as bodies. His work has impacted and spawned the fields of communications, thermodynamics, engineering, mathe­matics, and more. Surprisingly, the genius of his electromagnetic theory was not realized until after his death.
  4. GUGLIELMO MARCONI – This Nobel Prize win­ner did an immense amount of work to prove that wireless communication was viable. Some of his major accom­plishments include receiving the world’s first patent for a wireless-telegraphy system in 1896. In July 1897, Marconi demonstrated wire­less signals being sent over 12 miles for the Italian gov­ernment. That year, he also formed the Wireless Telegraph & Signal Co. Ltd (later re-named Marconi’s Wireless Telegraph Co. Ltd.).Marconi transmitted the first wireless signals across the Atlantic between Poldhu, Cornwall, and St. John’s, New­foundland in December of 1901 (a total of 2100 miles). He also patented a mag­netic detector, which long served as a standard wireless receiver. His work in short waves is credited with the cre­ation of the beam system for long-dis­tance communication.
  5. LES BESSER – Known as the founder of microwave com­puter-aided design (CAD), Besser wrote the SPEEDY pro­gram that offered a transistor database with high-frequency device parameters. He later authored COMPACT—the microwave-circuit optimization routine that became the industry standard. A prolific author, Besser has written many technical arti­cles and contributed to or co-authored numerous textbooks. Besser founded Compact Software, which is now part of Ansoft. His company, Besser Asso­ciates, is dedicated to continuing education.
  6. WILLIAM WEBSTER HANSEN – This physicist is regarded by some as the founder of microwave technology. As a Stanford Uni­versity physics undergraduate student, he became close friends with Russell Varian. The klystron actually was inspired by the two friends’ interest in X-rays. Hansen and the Varian brothers part­nered on many ideas, inventions, and pro­jects in the 1920sT940s. In 1937, Hansen began trying to solve the problem of detecting approaching aircraft. Togeth­er with the Varian brothers, he developed the klystron. In 1941, Hansen and his research group moved to the Sperry Gyroscope Co. in Garden City, NY. There, Hansen contributed to develop­ments in Doppler radar, aircraft blind­landing systems, electron acceleration, and nuclear magnetic resonance.
  7. HAROLD ISAACSON – World War II pilot and hero Harold Isaacson enjoyed devel­oping new products and put that love into the creation of one of the industry’s longest-running and least-known success stories—ARRA (Bayshore, NY). Isaac­son developed the firm’s lines of passive components—including its continuously variable attenuators—that are still widely used in military systems and commercial test equipment. Today, his wife Florence and son Roby run the company with the same family-oriented care (resulting in one of the lowest personnel turnover rates in the industry) that Isaacson established.
  8. DR. M.FUKUTA – In 1963, Fukuta joined Kobe Industries Co., which later merged with Fujitsu Ltd. He began working in the field of semiconductor devices including Si RF power transistors, Si ICs, and Si MOSFETs. In 1967, Fukuta invented “the mesh emitter transistor.” At ISSCC ’73, he presented the first paper on power GaAs FETs titled, “Mesh Source Type Microwave Power FET. ” In 1992, Fukuta became President of the Compound Semiconductor Group at Fujitsu and later helped to form Eudyna Devices.
  9. HP MICROWAVE SEMICONDUCTOR – HP Associates, an affiliate of Hewlett-Packard Co., supplied specialized silicon, ger­manium, and gallium-arsenide diodes for HP test systems. In 1964, it was renamed HP Microwave Semiconductor Opera­tion (MSO) and began marketing components to customers outside of HP. In 1978, HP MSO introduced the first fiber-optic transmitters and receivers for data communications. The next year, it announced the first integrated microprocessor development system to combine all of the tools that were needed by hardware and software engineers. In 2005, it became Avago Technologies.
  10. THOMAS RUSSELLRussell, a brilliant j microwave designer specializing in directional couplers, founded Krytar in the early 1980s as a way to pursue his love of engineering. His management style was based on the trust and respect of his employees and in placing value on their opinions. Russell developed one of the I first proprietary computer-aided-engineering (CAE) tools for the creation of microwave couplers, which he used for the design and development of many of the company’s standard product lines.
