Texas Instruments has introduced 150-mA, low-dropout linear regulators (LDOs) with dual-level voltage output for MSP430 microcontroller-based, battery-powered devices. Consuming the lowest quiescent current in the industry at 500-nanoAmps, the LDO’s voltage select (VSET) pin gives designers the ability to switch between two voltage levels to customize and cut power consumption in half during operation.

IDT has announced a new family of common public radio interface (CPRI )-based functional interconnect chip (FIC) solutions that bridge adjacent standards within the wireless infrastructure. These FIC solutions are the first such devices optimized to allow the common CPRI standard to span the interface between the wireless radio card and a Serial RapidIO-enabled base band processing system.

Radiometrix has introduced a new addition to its widely applicable, low cost LMT2/LMR2 transmitter/receiver series. Making use of the 458.525-459.1MHz UK frequency band (instead of the 433.875-434.650MHz EU band utilised in the previous versions), these higher power radio modules manage to increase the distance over which they can communicate to as much as 1km. This allows engineers to enhance systems that previously had insufficient range (or in...

LPRS, manufacturer of Europe's most popular wireless modules - EasyRadio, also offers a wide range of matching antennas to complete a communications system. Straight and right-angle designs are available covering the 433MHz, 868-900MHz and 2.4GHz frequency ranges. As a March offer, LPRS provides a free antenna with every ER900TRS-02 ordered on line. On top of this they offer a free delivery on all orders over £50 from the 1st of March until the ...

Texas Instruments has introduced the company’s second-generation ZigBee/IEEE 802.15.4 radio-frequency (RF) transceiver designed for the 2.4 GHz unlicensed ISM (industrial, scientific, medical) frequency band. Featuring state-of-the-art selectivity/co-existence and excellent link budget, the CC2520 targets a wide variety of ZigBee/IEEE 802.15.4 and proprietary wireless systems used in industrial monitoring and control, home and building automati...

Aimed at applications where RF engineers need to consider the interference effects of nearby vibrating machinery, Radiometrix has developed the HVR2 receiver. The HVR2 radio receiver module (a high vibration resistant version of the Radiometrix RLC2) utilises the company’s proprietary hybrid Direct Digital Synthesizer (DDS) local oscillator design to make it almost totally immune to mechanical vibrations at frequencies below 500Hz. When used in...

Tundra Semiconductor Corporation has announced the availability of the market’s first end-to-end RapidIO-enabled MicroTCA platform for wireless baseband. The platform, offers end-to-end 10 Gigabit RapidIO Interconnect for chip-to-chip and board-to-board links across the backplane.

Renesas Technology has announced the R2A60281LG, an ultra-compact 2G/3G dual-mode radio frequency (RF) transceiver IC that supports both 2G and 3G modes used in cellular communications. The device integrates in a single chip most of the high-frequency signal processing functions required by mobile phone handsets. Sample shipments will begin in March 2008 in Japan.

Admiral Microwaves has introduced an integrated RF Front End Module designed for 802.11b/g wireless local area network (WLAN) applications in the frequency range from 2.4 to 2.5GHz. Manufactured by US company, RF Arrays, the RWF111 consists of an integrated power amplifier, switch and low noise amplifier.
