About

The California Institute of Technology’s decision to cease sales of cryogenic low noise amplifiers and QRFH feeds led directly to the formation of Cosmic Microwave Technology, Inc. Dr. Sander Weinreb, the head of the Caltech group, has licensed his designs to CMT so these high quality components, used for radio astronomy and quantum computing, can continue to be produced to Dr. Weinreb’s exacting standards. The technical aspects of CMT are headed by Stephen Smith while Denise Smith manages the business aspects of the company. CMT also brings Hector Navarrete from Caltech, where he will continue to assemble amplifiers and feeds to the rigorous standards required. Caltech has untied the services of MVI engineering, used for all of the high quality machining required to produce the amplifiers and feeds, so CMT plans to continue the relationship with MVI.

Who We Are

Stephen Smith

Stephen Smith has been a designer of microwave hardware for 39 years, the last 7 of which were spent at Caltech as a research engineer under the direction of Dr. Sander Weinreb. His responsibilities included mentoring PHD and MS students, assisting with student-run experiments in the lab, managing the cryogenic amplifier production line, and designing cryogenic receivers for radio telescopes. Prior to Caltech, Stephen was the president of MMW Technology, Inc., which designed and built space qualified hardware for the Jet Propulsion Labs. Several current space missions are utilizing hardware that Stephen designed, more information is available on Stephen’s LinkedIn profile.
