RF Circulator Isolator, Inc. (RFCI) was incorporated in September 2012. RFCI acquired CIPL (Circulator/Isolator Product Line) business from RFMD, when RFMD decided to exit the CI business. Management, engineering team, support group, and oversea manufacturing were transferred intact to RFCI.

RFCI continues to provide excellent support to our customers, but without red tapes and large overhead. With this advantage, RFCI can bring final products to market sooner at a lower price, and support each customer with utmost care.

Our talented engineering team has a combination of many years of working in ferrite products. We design & manufacture the most challenging ferrite devices to serve in commercial markets. With support of oversea manufacturing, our prices are very competitive. Currently, we’re one of the biggest suppliers to the Base Station markets. We’re continuously improving our process to supply the highest performance components at lower price with the quickest time-to-market.

Our office is located in the heart of Silicon Valley:
