QuinStar Strategy and Legacy:

Throughout the years, we at QuinStar Technology have grown our business by servicing the needs of customers in the millimeter-wave and microwave sensors and communication field. As a key growth strategy, we have further broadened our products and services by acquiring synergistic businesses to better serve our customers.

We acquired DCL Inc. a small local electronic engineering firm in 1996.

In 1997, we acquired the complete assets of CERNEX Inc, a microwave amplifiers company in Sunnyvale, CA. We continued to operate this business in Sunnyvale as QuinStar Technology, Sunnyvale Division. In 2000, the facility was moved to our Torrance location to provide greater efficiency and responsiveness for our customers.

QuinStar acquired the manufacturing rights and all equipment and inventory of the Silicon IMPATT diode product line from Raytheon in 1998. The technology was developed for satellite communications and missile seekers in the mid 70s to 80s by Hughes Aircraft Company and later acquired by Raytheon. This was the foundation of our IMPATT amplifier and oscillator business, and we are the only commercial Silicon IMPATT diodes supplier in America today.

In 2002, we purchased all assets and the name of MPI / Millimeter Products, Inc. (www.milpi.com), a millimeter-wave components company in New Hampshire. The company was moved to our 44,0000 sq. ft. Torrance facility in 2003. This purchase expanded our waveguide and test components products similar to the TRG product line.

We expanded into the cryogenic amplifier business in 2004, with the acquisition of Berkshire Technologies, Inc. (www.berkshiretech.com). This acquisition enables us to further support scientific research customers.

After Mr. George Grund, the founder of PAMTECH, passed away unexpectedly in April 2010, QuinStar acquired PAMTECH’s assets and agreed to retain former employees of PAMTECH to assure continued operation of the company.

PAMTECH’s operation was moved to our Torrance location, and with the additional support of QuinStar resources, there was no interruption of PAMTECH production. We continue George Grund’s tradition of innovative and superior microwave component design, as well as continue support of legacy PAMTECH products.

The acquisition of PAMTECH, along with the acquisition of Berkshire Technology, provide us with the unique capability to offer cryogenic products to the radio astronomy science and quantum computing research fields.

In early 2012, QuinStar expanded and added another building and completed Phase 1 of the expansion and upgrade process of its facilities, adding approximately 15,000 square feet of manufacturing space.

During the recent years, we at QuinStar have significantly upgraded our antenna range, environmental test facility, and our machining capability.

We are a company of diverse abilities that continues to broaden our areas of expertise. Our goal is to provide efficient services and quality products to meet the many needs of our customers.
