New Chip With Filter Makes Bluetooth Simple Through Total Integration Including Antenna
*** Filter Gueston *** can anyone explain this??
What part does this filter part play on Bluetooth (tm)chip device! Does all chip makers have their own filters or are there really some IP holder, winners out there in filter scene?!! (Like ARM is a winner in it's own area)
This filter hype is ok for me but disturbing fackt is me not understanding anything on filters. Me stupid?

HANNOVER, Germany, Feb. 24 /PRNewswire/ -- Alcatel (NYSE: ALA - news) today announced its single-chip Bluetooth solution. The revolutionary design brings all Bluetooth functions, including RF, base-band, processor, memory, antenna and
filtering devices
into a single die package.
This unique approach brings simplicity to the implementation of Bluetooth in a wide range of products, from GSM handsets to PDA's, laptops, modems, etc. by minimising the need for RF expertise at the customer site.
``We have taken a hard look at the Bluetooth spec and have chosen not only to implement the mandatory features, but also all optional features,' said Steve Beckers, Director of the Alcatel Microelectronics RF Group. ``The driving principles behind this design are: complete, compact, and competitive. We have produced a single chip that can bring Bluetooth functionality to any device.'
The Alcatel Bluetooth solution is designed for low power consumption. The single 15 x 15 mm BGA package contains:
Complete radio
Base-band controller
ARM 7(TM)
Bluetooth 1.0 software stack on flash ROM with optional application
layer software.
Base band interfaces such as a high speed serial SPI-bus, UART and PCM (USB optional).
Antenna embedded in the Ball Grid Array (BGA) package
All external components embedded in the BGA package (RF input filter and de-coupling components)
The Alcatel Bluetooth chip uses the Bluetooth 1.0 software stacks from TTP Communications, a world leading independent supplier of digital cellular technology.
The Alcatel Bluetooth development platform is available to customers today. Volume production starts early 2001. |
