Ulrich Lothar Albert Rohde was born in Munich on May 20, 1940. His maternal grandfather, the chemist Franz Fischer, invented the process for liquefying coal to produce fuels. His father Lothar Rohde studied physics in Cologne and Jena before establishing the Physikalisch-Technisches Entwicklungslabor Dr. Rohde & Dr. Schwarz (PTE) in Munich with his university friend Hermann Schwarz in 1933.

Today Rohde & Schwarz GmbH & Co. KG is a global technology company with more than 13,000 employees, specializing in the fields of test and measurement, broadcast and media, cybersecurity, secure communications, and monitoring and network testing.

After completing secondary school (Abitur), Ulrich L. Rohde studied radio-frequency and communications engineering at the Technical Universities of Munich and Darmstadt. From 1965 to 1968 he worked as a development engineer with the United States Underseas Cable Corporation in Cologne. He then joined AEG-Telefunken in Ulm, where he was responsible for the military radio communications systems department from 1968 until 1974.

Since 1973 Ulrich L. Rohde has been a partner of Rohde & Schwarz GmbH & Co. KG in Munich. He pursued his career mainly in the USA, however. He served as the president of the Rohde & Schwarz USA subsidiary in Fairfield, New Jersey, from 1974 to 1982. After that he joined the RCA Corporation in Camden, New Jersey, as a managing director responsible for the military communications division. From 1985 until 1997 he was the president of Compact Software Inc. in Paterson, New Jersey, a company that he also owned. At the same location, he established the Synergy Microwave Corporation in 1985. Today he continues to serve as the chairman of the supervisory board of that company and also as the president of the Communications Consulting Corporation in Marco Island, Florida.

In 1977 Ulrich L. Rohde was appointed as a professor of electrical engineering at the University of Florida in Gainesville, where he teaches radio communications. Since 1982 he has also taught at the George Washington University in Washington D.C. as an adjunct professor of electrical engineering. In May 1997 he took on a third professorship with his appointment as a professor of electrical and microwave engineering at Oradea University in Romania.

Ulrich L. Rohde has received many awards and honors. Oradea University (Grosswardein) and ClujNapoca University (Klausenburg) in Romania have granted him honorary doctorates,and he has been chosen as a fellow of the Institute of Electrical and Electronics Engineers (IEEE).While filling important positions as an executive and company owner, he continued to build on his scientific qualifications. In 1978 he was awarded a doctorate in radio-frequency engineering in the USA and was invited to join the Epsilon Sigma chapter of the Eta Kappa Nu Association, in recognition of his excellent scholarship. Two years later he successfully completed an Executive Business Administration program at Columbia University in New York.

Guest professorships have led to stints at the Brandenburg University of Technology Cottbus Senftenberg, the University of Bradford in the UK, and the New Jersey Institute of Technology in Newark, New Jersey.

He was granted honorary professorships in radio-frequency and microwave engineering by the Brandenburg University of Technology Cottbus-Senftenberg in April 2002, and in 2017 by the University of the German Armed Forces Munich, member of the Faculty of computer science (cyber security). He is also a visiting lecturer at the Technical University of Munich.

In 2004 he submitted his dissertation on "A New and Efficient Method of Designing Low Noise Microwave Oscillators" to the Technical University of Berlin. Seven years after that he completed postdoctoral studies at the Brandenburg University of Technology Cottbus-Senftenberg with a thesis titled "A novel approach for generating active inductors for microwave oscillators – mathematical treatment and experimental verification of active inductors for microwave application".

In 2006, he was selected to be part of the Microwave Legends: “Through innovation and invention, these 45 people, places, and things have shaped the microwave industry”, Microwave & RF Magazine.

In 2011, he was selected to be on the list of Divine Innovators of November 2011, Microwave Journal http://synergymwave.com/articles/2011/11a/MWJ_cover.pdf

His companies develop and manufacture special microwave circuits and systems. Rohde has gained considerable recognition, in particular through his selection as the 2014 winner of the C.B. Sawyer Memorial Award, which recognizes entrepreneurship or leadership in the frequency control community, or outstanding contributions in the development, production or characterization of resonator materials or structures. Rohde was honored for the development of PC software that accurately analyzes noise in nonlinear circuits.

He received the IFCS I. I. Rabi Award at the IEEE International Frequency Control Symposium in 2015 in recognition of his intellectual leadership, selection and measurement of resonator structures for implementation in high-performance frequency sources, essential to the determination of atomic resonance. The award recognizes outstanding contributions related to the fields of atomic and molecular frequency standards, and time transfer and dissemination.

In 2015 he was appointed a life time Honorary Professor of RF & Microwave IIT Delhi, India; actively involved in supervising research scholars and PhD students.

In the same year 2015, he received the IEEE Region 1 Award for outstanding scientific contributions and leadership in the design and implementation of sophisticated RF technologies.

This was followed a year later by the Microwave Application Award from the IEEE Microwave Theory and Techniques Society (MTTS) for significant contributions to the development of low-noise oscillators. As a specialist in radio-frequency and microwave engineering, Rohde has been granted dozens of patents.

The University of the German Armed Forces Munich and the Brandenburg University of Technology Cottbus-Senftenberg appointed him an honorary senator in 2008 and 2011, respectively.
