Avago has announced a new fully matched wideband variable attenuator module for use in a wide range of broadband system applications. The ALM-38140, which is a 50MHz to 4 GHz PIN diode attenuator module, is a fully integrated solution that uses Avago's low distortion silicon PIN diodes housed in a miniature 3.8 mm by 3.8 mm by 1.0 mm multiple-chip-on board (MCOB) package with 6-pin configuration pads. This module is ideal for use wireless infrast...

LPRS has announced the launch of the latest narrowband radio modules from Circuit Design, Inc. The ultra-compact transmitter CDP-TX-05M-R and receiver CDP-RX-05M-R supersede the very successful CDP-TX-04S-R and CDP-RX-03AS/BS-R modules, maintaining their remarkable size and low power consumption (10mW) while offering multi-channel operation.

STMicroelectronics has introduced an IC that delivers superior sound quality from portable music players and feature-phones by excluding high-frequency interference from cellphones. This new device is ideal for the growing number of cellphones being shipped with music-playback capabilities, which iSuppli predicts will grow to exceed one billion handsets annually by 2010, representing more than 90 percent of the market. It will also protect other ...

Wolfson Microelectronics has announced the WM8993, its first device in a family of ultra low power audio hub CODECs for multimedia mobile phones and other feature-rich portable audio applications. Combining Wolfson's highly flexible audio hub architecture with the company's latest ultra low power and audio enhancement technology, the WM8993 delivers industry leading audio performance and over 100 hours of playback time in one compact, cost effect...

The latest advances in Murata's filter technology have led to development of a new SAW filter whose high power capability means it can be used as a top filter, replacing two interstage filters with a single component. In addition, the filter's external matching circuit requires just two inductors. This overall reduction in component count minimises a design's bill of materials and will be of particular benefit to OEMs making wireless consumer dev...

Yageo has announced the 1044 SMD LP Patch Antenna catering to GPS applications for smart phones, personal navigation devices and notebook computers. Yageo's 1044 SMD LP Patch Antenna is capable of delivering up to 80% more efficiency than traditional chip antennas while taking up 50% less space. Samples are already available to customers since April with mass production scheduled for May this year. Yageo expects to double GPS product shipments wi...

A new omni-directional antenna available from Admiral Microwaves will dramatically improve the performance of 802.11n wireless networks in a wide variety of installations. The S24493TS is low cost, compact and easy to install.

Ismosys, officially launched in March 09 as a new demand creation vehicle of the Spectrum Electronics Group, now has available ready-to-use wireless modules from LS Research making it simple and cost effective to add wireless capability to any product. The portfolio of module includes Pro-FLEX, 2.4GHz ZigBee Pro modules; Si-FLEX, sub 1GHz modules for long range applications; and Wi-FLEX, wifi modules.

Texas Instruments today introduced a new family of integrated load switches with controlled turn-on and quick output discharge to simplify subsystem load management. The TPS229xx family comes in an ultra-small 0.8 mm x 0.8 mm wafer chip scale package (WCSP) that is ten times smaller than a conventional discrete solution and supports space-constrained applications, such as portable media players, cell phones and portable navigation systems.

Fairchild brings designers of 3G smartphones, netbooks, set-top boxes and notebooks a module switch that isolates parasitic components to maintain signal integrity. The FSA1211 is a 12-port, single pole, single throw (SPST) analog switch that isolates the high speed bus from parasitic components in dual camera applications. Smartphones feature dual cameras and as these cameras move to higher and higher resolutions, parasitic components play a cr...
