Ltd. today announced the joint development of a small, power-stingy module for Bluetooth wireless connections in PCs, computer peripherals, telecommunications, and portable products. The alliance said it has combined a chip set from Mitel and Philsar with high-density packaging and radio-frequency technology from Matsushita for a high-performance and power-efficient model, compliant with the Bluetooth 1.0 standard. The Bluetooth module was designed to meet the cost, power consumption and small space requirements of mobile applications, said the three companies. The module measures 16-by-21-by-2.7 mm. It is expected to achieve power consumption of 20 mA in transmit mode and 17 mA in receive mode. According to the partners, this is an improvement of up to 43% in the transmit mode and up to 57% in receive mode compared to competing solutions. "The Mitel/Philsar solution enables our module to be competitive in the Bluetooth market," declared Keisuke Utsunomiya, general manager at Matsushita. "The silicon provides significant benefits in terms of low power, physical size and flexibility." The Philsar/Mitel chip setincludes a receiver architecture that uses a locally recurrent, globally feedforward structure to deliver robust performance under crowded conditions. The companies said this eliminates signal fading while consuming little power. "The collaboration will accelerate the adoption of Bluetooth in consumer systems for companies that lack the experience to integrate RF and baseband hardware and software into their host systems," said Ginji Nojima, Mitel Semiconductor's country manager in Japan. The module uses a chip set with Philsar's PH2401 radio transceiver and Mitel's MT1020A baseband controller. The PH2401 is a short-range radio transceiver, providing all of the circuitry required for complete transmit and receive functionality, according to Philsar. The new MT1020A from Mitel includes a Firefly embedded microcontroller core and the Bluetooth baseband peripheral (BBP) block, including audio codec, program memory, a general purpose analog-to-digital converter, and universal serial bus (USB) and UART host interfaces. Matsushita said it will make modules available under its Panasonic name brand in sample quantities by September.
