ISM Radio Modules Allow trouble-free implementation of wireless control functions

There are certain user applications where very simple ‘on/off’ control functions are all that are needed. Common examples, such as long-range lighting controls, alarm sounders, or machine shutdown safety systems, will normally require a microprocessor or dedicated remote control IC in addition to the radio module itself. Having to include such chips will incur extra cost, expand the system size, and increase the software overhead. This is clearly something of an irritation for engineers looking at what appear to be rather basic wireless designs, and which really shouldn’t need too much effort to implement.

Integrated baseband processors enable multimedia functions in low-cost GSM/GPRS phones

Integrated baseband processors enable multimedia functions in low-cost GSM/GPRS phones
Analog Devices has announced two highly integrated baseband processors designed to enable multimedia functions in low-cost GSM/GPRS cellular phones. The new SoftFone AD6721 reduces the cost and component count of entry-level multimedia phones, and the SoftFone AD6722 adds an integrated image signal processor for cameras up to 3 Megapixels and direct camera interface to eliminate the need for a separate camera coprocessor. Together, the devices bring a wealth of multimedia functionality to low-cost handsets, including both improved image quality and better sound.

CMOS RF transceiver is a complete solution for 3G mobile terminals based on W-CDMA

CMOS RF transceiver is a complete solution for 3G mobile terminals based on  W-CDMA
Analog Devices has unveiled the latest addition to its family of Othello(R) radios, the Othello-3. This CMOS RF transceiver provides a complete solution for 3G mobile terminals based on the W-CDMA air interface standard. Leveraging ADI's Othello direct-conversion architecture and an innovative low-noise transmitter, the Othello-3 (AD6551) transceiver eliminates the need for transmit-path surface acoustic wave (SAW) filters. In addition to simplifying the RF section in 3G mobile terminals, Othello-3 reduces board space by 40 percent over competing solutions – key drivers to delivering smaller, more cost-effective 3G handsets.
