TI introduces high-temperature transceivers for oil exploration equipment

TI introduces high-temperature transceivers for oil exploration equipment
Two new ceramic-packaged transceivers from Texas Instruments enable data communication in high-temperature applications. The devices feature no thermal shutdown, meeting the demanding requirements of oil exploration applications, such as downhole drilling. The SN65HVD11SJD 3.3-V single, half-duplex RS-485 transceiver and the SN65HVD233SJD 3.3-V CAN transceiver are the first two parts for an extended temperature range of -55C to 210C to be released from TI and are from a complete signal chain and power roadmap targeting applications operating in harsh environments. Future products will include data acquisition, processing and power managment devices.

25kHz Narrowband Transceiver from Radiometrix

The TR3M has been developed by the team of wireless communications experts at Radiometrix. It is high-end multi-channel narrowband transceiver that operates in the European 868MHz band (though custom variants for any 3MHz frequency block from 860-870MHz are available on request). It supports data rates of up to 5kbits/s, and has a usable range of over 500m. Employing a 1200baud dumb modem it allows transmission across 80 different channels.

TI introduces common mode, 70-V, fault-protected RS-485 transceiver family

TI introduces common mode, 70-V, fault-protected RS-485 transceiver family
Texas Instruments has introduced a family of +/- 70V, fault protected RS-485 transceivers that achieve overvoltage protection with no external termination needed. These low-power devices serve as drop-in upgrades to existing RS-485 designs without costly board redesigns. The new half- and full-duplex transceivers simplify design in industrial automation, motor control and heating, ventilating, and air conditioning (HVAC) equipment.

Peregrine Semiconductor Claims Breakthrough in Mobile Antenna Tuning

Peregrine Semiconductor Claims Breakthrough in Mobile Antenna Tuning
Peregrine Semiconductor has claimed a breakthrough in the solution to mobile antenna tuning. The Company’s new DuNE Technology, a patent-pending design methodology made possible by Peregrine’s UltraCMOS process and HaRP design innovation, has enabled a single-die tunable capacitor circuit – referred to as a Digitally Tunable Capacitor (DTC) – which meets the high-performance demands for antenna tuning in leading-edge cellular and mobile applications. These demands include superb power handling and linearity; low power consumption; and highly integrated in a small form factor. For more than 20 years, the RF researchers have attempted to address these challenges with a variety of micro-electromechanical systems and ferroelectric materials technologies, each having its own merit yet unable to integrate the features and functionality enabled by Peregrine’s DuNE Technology.

TI enables RFID tag reliability

Texas Instruments and 3M Library Systems today celebrated a 10-year relationship that has created of one of the major markets for radio frequency identification (RFID) technology. To date, millions of TI Tag-it HF-I chips help libraries track periodicals in 3M Library Systems worldwide. Developed with a memory that reliably retains its data for an estimated 60 years at 131 degrees Fahrenheit (55 degrees Celsius), TI supplies its durable, high-quality HF chips in inlay format to 3M Library Systems, which manufactures RFID labels to tag library assets as part of its full-line of RFID solutions. The 3M RFID System streamlines the checkout and return, sorting and inventory management of library materials to better serve customers.
