                              SiGe meets high-volume demand with efficient, low-power solution                              Ottawa, Ontario — June 5, 2001 
                              Ottawa, Ontario – June 5, 2001 – SiGe Semiconductor today announced that the PA2423MB power amplifier has been                             selected by Cambridge Silicon Radio (CSR) for integration on CSR’s BlueCore01 modules. The modules provide a                             complete, efficient, and low-power solution that accelerates time-to-market for Class 1 Bluetooth-enabled PCs, workstations                             and PCMCIA cards. 
                              “We are very excited that CSR chose our PA2423 power amplifier,” said Jim Derbyshire, president and CEO, SiGe                             Semiconductor. “Collaborating with a world leader to provide integrated Bluetooth solutions has fueled our success in this                             market, and guaranteed our penetration into some of the first Bluetooth products to hit the streets.” 
                              The PA2423MB, as well as the BlueCore01 module, are fully certified to the Bluetooth specification, and have been                             integrated into qualified products from companies including Brain Boxes, Fujitsu, IBM and Sony. 
                              “SiGe’s on-time delivery of volume production quantities contributed to our success in being first to market with a qualified                             Class 1 Bluetooth module,” said Glen Collinson, Vice President Marketing, CSR. “We are impressed that they were able to                             deliver a power amplifier that was so easy to implement, while achieving our requirements for minimized form factor and                             power consumption.” 
                              PA2423MB delivers efficient, easy to implement solution CSR chose the PA2423MB in part because it is the most efficient                             power amplifier on the market. The PA2423 delivers +22.5 dBm output power with 45 percent power-added efficiency when                             operated in class AB mode. This leading performance extends the transmission range, and overcomes antenna and filter                             losses while meeting regulatory requirements. 
                              This level of performance was achieved through the use of silicon germanium BiCMOS processes, which also enable high                             integration and low power consumption for extended battery life. With integrated patent-pending output power control and                             ramping circuitry, the PA2423MB eases implementation, and eliminates requirements for external control ICs, saving the                             associated board space, cost, and power consumption. 
                              CSR’s BlueCore01 module dramatically shortens design cycle CSR’s Class 1 Bluetooth module provides a complete, fully                             qualified solution to system designers. The module is based on the company’s BlueCore01 technology, which includes the                             industry’s first integrated CMOS-based radio, baseband and microcontroller. The module also includes a fully integrated                             Bluetooth software stack and CSR’s CMOS radio frequency (RF) transceiver, complete with support for a USB connection                             and piconets. 
                              Cost and Availability The PA2423MB is currently in volume production, and costs $1.44 in 10K quantities.

                              About CSR CSR (Cambridge Silicon Radio) specialises in providing single chip radio devices to the global market for short                             range radio communications, including Bluetooth. The company’s mission is to create the most highly integrated radio                             devices available, fabricated using standard CMOS technology, to provide its customers with the low cost of ownership of                             high quality digital radio. 
                              CSR was the first company to offer a fully integrated 2.4GHz radio, baseband and microcontroller Bluetooth solution on one                             CMOS chip, with its BlueCore™01. CSR’s BlueCore01 is the world’s first true single chip Bluetooth solution. Together with                             the Flash ROM containing the CSR Bluetooth software stack, it provides a fully compliant Bluetooth solution for data and                             voice communications. The design is optimised to require very few external RF components which facilitates a rapid design                             of the motherboard, and can therefore decrease time to market and lower overall cost.
