Vendor Introduction

Founded in January 2008, RFaxis Inc., headquatered in Irvine, California is an innovative fabless semiconductor company specializing in the design and development of RF Front-end Integrated Circuits (RFeIC). These first of their kind chips are designed to specifically address the critical path needs of the burgeoning wireless market. RFeIC

With its patent pending technologies, RFaxis leads the way in next-generation wireless solutions designed for the multi-billion dollar Bluetooth, WLAN, MIMO, Zigbee, WiMAX, and mobile phone markets. Leveraging BiCMOS process in conjunction with its own innovative approach and technology, RFaxis is home to the world's first RF Front-end Integrated Circuit (RFeIC).

RFaxis offers system designers and product developers highly integrated, single-chip, single-die RFeICs that significantly simplify the design task and substantially improve performance. Moreover, these ICs also drastically reduce the system noise and lower end product cost.
