CSEM Develops Transceiver that Expands Long-life, Miniaturisation Expectations for Implantable DevicesJuly 26, 2012 – 8:20 am
Switzerland’s CSEM has developed an ultra-low power 2.4-GHz transceiver platform. The IcyTRX platform consumes less than 10 mW, making it suitable for Bluetooth low energy, WirelessHART and IEEE802.15.4 applications. Medical implants and body-sensor networks, which require miniaturised components with extended battery life, are among the products that will benefit from the device, according to the private research and technology organisation.
Short-range wireless applications are increasingly focusing on the 2.4-GHz frequency band due to its worldwide availability and extended data-rate compared with sub-GHz frequency bands, notes CSEM in a press release issued today. However, this higher frequency typically consumes more power. Many RF transceivers currently on the market were developed for Bluetooth, Zigbee and so forth, and are not optimized for low powerconsumption.
The IcyTRX platform has been designed with the goal of reducing power consumption as well as allowing the use of small coin cell batteries. This parallel-track approach reportedly extends battery life and miniaturisation far beyond what is obtainable today.
An integrated design foregoes external matching components and yields a very small footprint and variable data rate up to 2MBits/sec. IcyTRX is integrated into a standard digital 90-nm CMOS process and is designed to exceed the specifications and requirements of Bluetooth low energy, the physical layer of IEE802.15.4 as well as proprietary standards.
IcyTRX is available as a silicon-proven IP and under license for integration into RF SoCs. Samples are available.Norbert Sparrow
