SiW1722 UltimateBlue IC Features On-Chip RF Matching That Lowers

Cost and Accelerates Time to Market

Silicon Wave and RF Micro Devices (Nasdaq: RFMD) today announced their newest UltimateBlue(TM) Bluetooth(R) single-chip IC, the SiW1722, designed exclusively to meet the rigorous RF, power and cost requirements of CDMA mobile phones using CDMA chipsets with an integrated Bluetooth baseband. Implemented on CMOS process technology, the highly integrated direct conversion radio modem's unique on-chip RF matching feature helps drive down cost by eliminating all external RF matching components, making it ideal for direct PCB insertion. The new SiW1722 single-chip solution will be on display in the RFMD Booth #1821 at CTIA Wireless 2004 in Atlanta, Georgia, March 22 - 24, 2004.

"The SiW1722 Bluetooth radio modem has been optimized to ease the integration of Bluetooth technology into CDMA mobile phones," said Steve Brown, vice president business development and product marketing for Silicon Wave. "The unique on-chip matching of the SiW1722 allows direct connection to the antenna which simplifies design and reduces component count. The net result for an OEM is a lower cost mobile phone that can be introduced to market faster."

Frank Morese, vice president of wireless connectivity at RF Micro Devices, said, "The SiW1722 provides our customers a highly integrated Bluetooth solution that features the best combination of price, performance and time to market. Additionally, this new solution enables us to better support our increasing base of customers who are engaging us to provide more comprehensive wireless solutions."

The SiW1722 IC is designed to consume up to 20 percent less power than previous Silicon Wave products. Its direct conversion architecture allows digital filtering for excellent interference rejection and fewer spurious responses resulting in superior RF performance.

Additional Key Features of the SiW1722 Radio Modem

-- Supports all popular mobile phone reference clock frequencies.

-- Achieves up to -85dBm receiver sensitivity and up to +4dBm transmitter output power over extended operating conditions.

-- Fast hardware based Automatic Gain Control (AGC) circuit dynamically adjusts receiver for optimal performance.

-- Fully compliant to Bluetooth Specification Version 1.2.

Availability and Packaging

Samples of the SiW1722 IC are available exclusively from RF Micro Devices, Silicon Wave's global channel partner for its CMOS single-chip radio processors and stand alone radio modem Bluetooth solutions. The SiW1722 is available in a 5mm x 5mm QFN-32 pin package or as bumped die. Volume production is anticipated in Q3 2004.
