RFaxis Inc. has begun volume production of what it touts as the industry's first and only single-chip/single-die WiFi/Bluetooth combo RF Front-end IC (RFeIC) in pure CMOS, the RFX8422S. The company has also started sampling its RFX8422, a drop-in replacement of RFX8422S, for applications that require reduced maximum package height of 0.4mm.

The RFeICs claim to provide key RF functions for dual-mode WiFi/Bluetooth operation in a typical smartphone or other mobile devices. Both parts include high-efficiency linear power amplifier (PA), low noise amplifier (LNA) and single-pole triple-throw (SP3T) antenna switch, all integrated into a monolithic die, and are offered in an ultra-compact 2.5 x 2.5mm 16-pin Quad-Flat Non-Lead (QFN) package. Developed and manufactured in the industry's most cost-effective bulk CMOS process, the RFX8422S and RFX8422 family of complete "3-in-1" RFeICs provide modern RF performance, and are pin-compatible with similar offerings from competitors on the market today, noted the firm.
