Sierra Microwave Technology was founded in 1985 in Sacramento, California. The company, from the beginning, developed a reputation for producing very reliable parts for the military and space industries. Very wide frequency bands, low loss performance, and exceptional quality were what set Sierra apart from competitors.

In 1992, Sierra relocated to Georgetown, Texas to take advantage of the lower operating cost in that region. Sierra spun off its amplifier group prior to moving to Texas. This allowed a concentration on the product lines which had always formed the core of Sierra’s business: Isolators, Circulators, Equalizers, Filters, and Pin-Diode Switches.

In their 20,000 square foot facility was designed to optimize productivity and a heavy investment in CAD, manufacturing, and test equipment together with Sierra’s advanced designs helped us develop our reputation as a supplier of parts of the highest quality and performance.
