Apple on Tuesday said it has entered a multi-billion-dollar deal with chipmaker Broadcom to use chips made in the United States.

Under the multi-year deal, Broadcom will develop 5G radio frequency components with Apple that will be designed and built in several facilities, including Fort Collins, Colo., where Broadcom has a major factory, Apple said.

Broadcom shares were up 2.2% after the announcement.

The chipmaker is already a major supplier of wireless components to Apple.

Apple said it will tap Broadcom for what are known as film bulk acoustic resonator chips.

The FBAR chips are part of a radio-frequency system that helps iPhones and other Apple devices connect to mobile data networks.

“All of Apple’s products depend on technology engineered and built here in the United States, and we’ll continue to deepen our investments in the US economy because we have an unshakable belief in America’s future,” Apple CEO Tim Cook said in a statement.

Apple said it currently supports more than 1,100 jobs in Broadcom’s Fort Collins FBAR filter manufacturing facility.
