RFX333 Single-Pole Triple-Throw (SP3T) Switch Redefines Process Technology and Cost Structure of Wi-Fi/Bluetooth RF Switches for Smartphones and Mobile Devices
IRVINE, Calif. — (BUSINESS WIRE) — July 17, 2013 — RFaxis, Inc., a leading fabless semiconductor company focused on developing innovative, next-generation RF solutions for the wireless connectivity and cellular mobility markets, announced today that it has started volume production of its RFX333, a single-pole triple-throw (SP3T) switch optimized for 2.4GHz Wi-Fi/Bluetooth combo chips used in smartphones, tablets and other mobile devices. The RFX333 is developed and manufactured in the industry's most cost-effective bulk CMOS technology, and pin-compatible with incumbent solutions in the market today that use more expensive Gallium Arsenide (GaAs) or Silicon-On-Insulator (SOI) processes.
"With Qualcomm's recent announcement of its RF360, the global RF industry is undoubtedly witnessing an accelerated acceptance of CMOS based RF front-end components including PAs and switches," commented Mike Neshat, chairman and CEO of RFaxis. "We saw GaAs pHEMT switches displaced by SOI on many platforms in the last couple of years. We are now offering our Wi-Fi SoC partners and ODM/OEM customers with pin-compatible, alternative RF switch solutions based on pure CMOS at a significantly reduced price. By adding RFX333 to our portfolio, RFaxis is rapidly becoming a one-stop shop for high-performance, and yet the most cost-effective RF solutions for wireless connectivity products, including complete RF Front-end ICs ( RFeIC), high-power PAs and now switches."
The RFX333 is a single-pole, triple-throw (SP3T) antenna switch developed in bulk CMOS technology. The device is optimized for wireless applications requiring high linearity and low insertion loss, such as WLAN IEEE 802.11b/g/n and Bluetooth in the 2.4GHz frequency range. The RFX333 has simple and low-voltage CMOS control logic, and requires minimal external components. All DC-blocking capacitors are integrated on-chip to minimize PCB footprint. Assembled in an ultra-compact, low-profile 1.6x1.6x0.45mm 12-Pin Quad Flat No-Lead (QFN) package, the RFX333 provides an ideal RF switch solution for handset, smartphone, tablet and other mobile platforms.
