Kaben Wireless Silicon

Ottawa, ON - May 13, 2003 - Kaben Wireless Silicon Inc., a developer of mixed-signal, intellectual property (IP) blocks for wireless manufacturers, announced today that SiGe Semiconductor has licensed Delta-Sigma () Fractional-N Synthesizer IP provided by Kaben Wireless Silicon.

SiGe Semiconductor has licensed Kaben Synthesizer IP for use in its GPS IC product line. "Designing a fractional-N synthesizer would have taken years to develop in-house," said Jeff Robillard, product line manager, SiGe Semiconductor. "Using the synthesizers from Kaben Wireless Silicon reduces development time, allowing us to meet the compressed design cycle and delivery windows characteristic of today's market conditions."

synthesizers solve several problems faced by radio systems designers. ICs based on these synthesizers feature small frequency step sizes, as well as reduced phase noise and spurious tones. The synthesizers also add flexibility in frequency planning.

synthesizers are now commonly used to reduce the number of analog components in a system when used in a direct modulation architecture. Direct modulation is appropriate in standards that require FSK modulation such as Bluetooth. This allows the baseband digital data to be directly converted to the transmit frequency by having the synthesizer output the modulated frequency. This eliminates many analog components such as mixer stages that would normally be used to upconvert or modulate the transmitted signal.

Tom Riley, recognized as one of the early pioneers in Fractional-N synthesizers and CTO for Kaben Wireless Silicon said, "It has taken many years to bring synthesizers to today's level of predictable performance."

"Kaben's Synthesizer IP block enables SoC manufacturers to achieve the desired system performance in a reduced time frame." said Seste Dell'Aera, Kaben's VP Marketing. "This mature technology can be licensed for integration into wireless systems such as Bluetooth, cable modems, and WLAN 802.11a/b/g."
