Several companies unveiled products at the Bluetooth Developer's Conference, which took place on Dec 11 to 13 in San Francisco.
-
SiGe announced its 2.4 GHz SE2520L linear power amplifier for Class 1 applications, which offers 22-dBm linear output power and a typical power consumption of 138 mA. Price is 80 cents (100,000).
-
Silicon Wave introduced the SiW1701 and SiW1702 CDMA-chip-set-compatible and SiW1703 GSM-chip-set-compatible radio modems, each selling for $5 (100,000), and various 32-bit ARM-based baseband processors with 256 kbytes of ROM or flash.
-
MindTree Consulting announced its EtherMind Bluetooth baseband architecture, which complies with Bluetooth 1.1 and is available as a synthesizable Verilog core and includes Link Manager Protocol and host-controller-interface firmware.
-
Extended Systems has released an add-on module supporting the Bluetooth hard-copy-cable-replacement profile to its Xtndaccess Blue software-development kit with support for the basic printing profile. New test products included Agilent's E1852 Bluetooth test set for establishing Bluetooth links and measuring key RF parameters.
-
Tektronix has released Version 2.2 software for its BPA100 Bluetooth Protocol Analyzer, which offers extended analysis of the Bluetooth stack and a revamped user interface.
-
Tality announced that its Bluetooth baseband-controller Internet Protocol and lower protocol stack have received 1.1 qualification.
-
The Bluetooth Special Interest Group has released a human-input-device definition for devices such as mice and keyboards; adoption, definition, and prototype devices should emerge by midyear.
-
Conexant offered a Bluetooth/V.90 modem reference design that integrates Impulsesoft's iBTStack embedded protocol stack onto the Conexant CX81400 baseband controller. Conexant also announced an embedded-stack-development platform for its ARM7TDMI baseband controller.
-
Oki Semiconductor announced a Bluetooth reference design, co-developed with Adamya, a Bluetooth Ethernet-access-point reference design; co-developed with Ubicom, and a Bluetooth module-system-development kit measuring 95×55 mm.
-
Adamya has ported its C-Blue Bluetooth baseband and protocol stack to the Tensilica Xtensa configurable microprocessor architecture.
