MaxLinear Inc., a Carlsbad business that makes integrated circuits for broadband communications, plans to move its headquarters in 2014 while staying in Carlsbad.

MaxLinear (NYSE:MXL) said in a recent securities filing that it plans to move to 45,000-square-feet of space at 5966 La Place Court, just north of McClellan Palomar Airport.

“We’ve kind of outgrown the space we’re in now,” said Adam Spice, the company’s chief financial officer. The new location will include more lab capacity and engineering space, Spice said.

In a February securities filing, MaxLinear said the lease on its 29,000-square-foot main office in Carlsbad will expire in August. The annual filing from February also mentioned facilities in Irvine and San Jose, as well as Japan, China, Taiwan, South Korea and India.

Spice said MaxLinear was expanding in other markets and recently opened an office in Atlanta.

The new lease in Carlsbad will last five years and six months. MaxLinear will pay $56,000 in base monthly rent; the sum will increase to $65,000 at the end of the term. The Campus Carlsbad LLC is the business’s new landlord. The lease term begins on March 27 or five days after tenant improvements are complete — whichever is later.

MaxLinear reported a net loss of $4.9 million on net revenue of $31.8 million in the quarter that ended Sept. 30. The company contracts with an outside manufacturer to produce its microchips. It recently announced a deal to provide one of China’s top TV manufacturers with tuners.
