Integrated Device Technology has moved its Fort Collins operations after a neighbor in its building, Advanced Energy Industries, took over IDT’s space.

Headquartered in San Jose, IDT employs a team of engineers in Fort Collins that performs research and development for power and consumption management of high-end computer servers used in cloud computing and mobile applications.

IDT’s 15 employees didn’t have to move far. The old office was at 4424 Innovation Drive; their new address is 4856 Innovation.

IDT will lease 12,500 square feet in the newer building, in which it hopes eventually to expand, said Lisa Carney, production control manager. The company, founded in 1980, has operated a site in Fort Collins since 2006.

The company is moving because as its lease in the older building expired, AE reached a deal with its landlord to take over the entire building.

AE representatives said they could not comment on the move.

AE is in the solar industry; it makes parts used in solar installations. Its move comes amid a restructuring that began in the fall. That effort has included outsourcing manufacturing of its solar subassemblies from Fort Collins to Shenzhen, China.

IDT, meanwhile, has now entered into a “long-term” lease with Oakridge Innovation, which owns the nearly 24,000-square-foot building, said Jason Ells, senior vice president of Cassidy Turley Fuller Real Estate, which brokered the transaction. He declined to say when the lease would expire.

The building contains an electronics testing laboratory, offices and conference rooms.
