RF Micro is shutting down its development efforts focused on wireless local area networks (WLAN) chips but will continue to support its WLAN products, the company said late Monday.

The decision means cuts in RF Micro’s workforce in San Jose, CA and the closing of offices in Moscow and Leuven, Belgium. The company said the reductions would save between $18-22 million a year.

Bob Bruggeworth, chief executive officer of RF Micro, said the company would focus on “our greatest opportunities for long-term, profitable growth” in such areas as cellular power amplifiers and cellular transceivers.
