New! CC1190 sub 1 GHz range extender

The latest addition to TI low-power RF's product portfolio is the CC1190, a highly-integrated, cost-effective RF range extender for low-power wireless applications at 850 to 950 MHz. The CC1190 works with TI's CC1101 sub-1 GHz transceiver and the CC430 or CC1110 systems-on-chip. The CC1190+CC1101 solution can provide up to +149-dB link budget. The single-chip CC1190 integrates a power amplifier (PA), a low-noise amplifier (LNA), switches and RF matching, which eliminates expensive discrete components, simplifies design layout, reduces test time, improves RF performance and shrinks overall board space.

Start development today with the CC1190EMK evaluation module kit. Combo boards with a transceiver and CC1190 will be available 2Q 2010.

Implementing 'Diversity' Using Low Power Radios
This application note describes and compares three different diversity techniques using Low-Power RF radios. The techniques considered are using two antennas with one receiver, two antennas with two receivers, and redundant transmission of information over two frequencies.

New features revealed on CC1101! Higher data rates and 4-FSK modulation
CC1101 Data Sheet has been updated with 4-FSK modulation. 4-FSK can be operated up to 300 kBaud, which corresponds to 600 kbps.

DN508 Frequency Scanning using CC430Fx, CC110x, and CC111xFx
This design note shows the necessary steps to successfully scan through a frequency band covering n numbers of channels, and find the strongest signal in the band.

DN507 FEC Decoding
The design note shows how the FEC decoding implemented in HW on the CC1100, CC1100E, CC1101, CC1110Fx, CC1111Fx, CC1150, CC2500, CC2510Fx, CC2511Fx, and CC2550 can be implemented in SW. This is in particular very important for the CC430Fx device, which has the same radio as the CC1101 and CC1110/11Fx but without HW FEC included.
More
DN119 Asynchronous Serial Mode for CC111xFx and CC251xFx
This design note shows how the CC111xFx and CC251xFx can be configured for asynchronous serial mode. This mode can be used in applications that need to transmit and/or receive data packets not fitting with the standard packet format supported by the CC111xFx and CC251xFx.

And the Winner is…. Bluetooth® Low Energy

The Bluetooth SIG announced the Bluetooth Innovator of the Year earlier this month. The Innovation World Cup 2009 drew more than 250 entries illustrating the wealth of opportunities for product development with the new Bluetooth low energy wireless technology. Texas Instruments and 14 other industry experts participated in the panel of judges, selecting a winner and three finalists whose ideas were recognized at the award ceremony held in-line with the Wearable Technologies Show at ispo 2010 In Munich earlier this month.

Innovation World Cup 2009 Bluetooth Innovator of the Year

The winning idea by Edward Sazonov, PhD, The Fit Companion, is a small, unobtrusive sensor that when clipped-on to a user's clothing or integrated in to a shoe, provides feedback about their physical activity. The data, transmitted via Bluetooth low energy technology, can help individuals to lose weight and achieve optimal physical activity. The other finalists' Bluetooth low energy enabled solutions include a fitness monitoring solution specifically created for snow sports, a wrist watch designed for swimmers and a fertility manager and body monitor.

Ideas for the Bluetooth Innovation World Cup 2010 can be submitted from June 1st – August 31st 2010.

Adhoco.S1 radio-controlled power switch Home Automation certified
adhoco.S1 Home

The ZigBee® Alliance recently announced the certification of a number of home automation products, including the adhoco.S1 radio-controlled power switch, using Texas Instruments' CC2430 ZigBee system-on-chip. The adhoco.S1 is a small, combined light on/off actuator and light switch sensor fitting behind light control switches of any type at 230 VAC operation. It features an indicator LED and a multi-purpose pushbutton. The certified products will be branded with the ZigBee Certified logo and the ZigBee Home Automation icon on product packaging and advertisements to clearly communicate interoperability to the marketplace.

SignalFire Gateway-in-a-Stick

SignalFireSignalFire Telemetry Inc has introduced its Gateway-in-a-Stick™ as the latest component in its SignalFire Remote Sensing System™ (SFRSS). The Gateway-in-a-Stick is a rugged, integrated device that combines a high gain antenna with gateway electronics on a single, easily mounted package. It uses Texas Instruments' CC1110 inside, along with TI power management products.

The Gateway-in-a-Stick combats a common problem with RF networks, which are being increasingly used to provide wide-scale (10's or 100's of square miles) monitoring and control of remote devices. A gateway consists of an electronics module plus antenna. These two devices have different location requirements making an optimal solution impossible. SignalFire has surmounted these challenges with its unique Gateway-in-a-Stick design, which integrates the electronics module and antenna into a single structure that can be optimally mounted. It connects to a control system via an RS-485 Modbus interface. In addition, power consumption has been significantly reduced making it ideal for solar powered applications.
