Radio modem certified for CDMA and 3G handsets
The SiW1712TM UltimateBlue radio modem has received certification for use with CDMA chipsets with an integrated Bluetooth baseband.
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% 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.
In addition, 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; has a fast hardware-based automatic gain control (AGC) circuit that dynamically adjusts receiver for optimal performance; and is fully compliant with Bluetooth Specification Version 1.2.
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 5 x 5mm QFN 32-pin package or as bumped die.
Volume production is expected in Q3 2004.
