Fabless semiconductor firm RFaxis Inc of Irvine, CA, USA, which designs RF semiconductors and embedded antenna solutions for the wireless connectivity and cellular mobility markets, says that its CMOS RF (radiofFrequency) front-end integrated circuits (RFeICs) are powering the latest generation of wireless sound bar and subwoofer systems by Zylux Acoustic Corp, a designer and developer of consumer electronics and loudspeaker systems. Zylux products feature RF modules by Atmel which use the RFaxis RFX5000 5GHz RF front-end with Ozmo2000 chipset for 802.11a 5GHz Wi-Fi Direct models, as well as modules by Freesystems with RFaxis’ RFX2402C 2.4GHz RF front-end paired with the MuChip FS2219 wireless audio SoC (System-on-Chip).
“The home entertainment market continues to be a growing sector. The maturity of the home theater systems requires technologies like ours to enable Home Area Networks (HAN) to go beyond file transfer and Internet access to more complicated operations such as multimedia streaming,” said RFaxis’ chairman & CEO Mike Neshat. “High-fidelity and high-definition audio streaming over proprietary RF connections and Wi-Fi Direct are an on-going trend.”
“RFaxis’ technology has enabled us to offer our customers high performance and high reliability wireless audio products at very competitive prices,” added Wyatt Briant, president of Zylux America.
RFX5000 is a fully integrated, single-chip, single-die CMOS RFeIC which incorporates all the RF functionality needed for a typical IEEE 802.11a/n WLAN system operating in the 4.9-5.85GHz range. Similarly, RFaxis' RFX2402C incorporates all RF front-end functionality needed for 2.4GHz IEEE 802.11b/g/n WLAN applications. The RFaxis RFeIC architecture integrates the PA, LNA, transmit and receive switching circuitry, the associated matching network, and the harmonic filter all in a CMOS single-chip device.
