The San Jose chip maker will supply the Tokyo-based manufacturer with it's CMOS-based RN5200 chips for us in client and access point products.

Resonext Communications, an emerging WLAN semiconductor company, announced today that it has established a partnership with Taiyo Yuden, a $1.3 billion Japanese multinational manufacturer of surface mount and leaded passive components, power electronics modules, and power supplies.

Resonext agreed to supply Taiyo Yuden with IEEE 802.11a chipsets targeted at both commercial and consumer platforms. Taiyo Yuden will develop and commercialize module solutions for the 5GHz WLAN market.

Resonext Communications has secured $68.5 million in funding in the last two years. Resonext is a privately held company with corporate headquarters in San Jose, Calif.

Taiyo Yuden is a 52-year-old Tokyo-based manufacturer with expertise in multilayered component manufacturing, high-frequency circuitry design, advanced assembly techniques and evaluation technologies - with aggressive Bluetooth research, development and strategic partnerships.

Taiyo Yuden claims approximately 50% of the worldwide market in high-frequency multilayer chip inductors used in cellular phone applications. Taiyo Yuden employs more than 18,000 people, and the company's North American subsidiary, Taiyo Yuden (U.S.A.), operates sales and engineering offices in Chicago, San Jose, San Marcos, Dallas and Raleigh.

About the Resonext Chipset
The Resonext RN5200 chipset family uses the same design for client and Access Point (AP) platforms. The chipsets incorporate the company's True Zero-IF 5GHz CMOS radio, designed to produce a reduced Bill of Materials (BOM) cost and low power consumption. According to Resonext, the chipset has a flexible Media Access Control (MAC) architecture designed to support differentiation and the evolving IEEE standards. The architecture also includes AccuChannel equalization technology, which the company claims delivers up to a 32% range increase across data rates.

Both client and AP chipsets consist of two chips -- a highly integrated RF chip and a baseband/MAC IC -- each built on the standard 0.18-micron, 1.8-volt CMOS process. Resonext's RN5200 chipsets are fully 802.11a compliant, the company said, and support the 5.15-5.35GHz UNII bands and up to a 54Mbps data rate.

Built-in support for IEEE drafts for Security (802.11i), Quality of Service (802.11e), Dynamic Frequency Selection and Transmit Power Control (802.11h) is also included. The AP chipset, features Access Point on a Chip (APoC) architecture, which enables lower cost, higher performing, feature-rich AP platforms, according to the company.

Resonext will conduct private demonstrations of its 802.11a chipset in conjunction with Network+Interop in Tokyo this week. The chipsets are sampling now and are slated to be in production this fall.
