Bolstered in part by a $500,000 grant from the state of North Carolina, RF Micro said it plans to spend $75 million to expand its Greensboro facilities.

The wireless and radio frequency device company said it also would add 75 jobs.

Gov. Mike Easley announced the grant and expansion plan. The grant is from the One North Carolina program which is designed to help the state recruit and expand quality jobs by “providing financial assistance to businesses or industries deemed by the governor to be vital to a healthy and growing state economy,” according to the governor’s office.

RF Micro said the new jobs would be for manufacture of wafers to be used in cell phones. The jobs will pay an average of $36,000.

The company said $50 million would be spent on machinery and equipment and $25 million to building improvements.
