Microwave Engineering Europe - December 2007 - (Page 36) 36 PRODUCTS 50-channel LEA-5 GPS module series boasts an acquisition performance of less than one second and -160 dBm acquisition and tracking sensitivity. The leading Swiss provider of GPS chips, modules and services, u-blox AG, has announced the launch of two GPS modules that set new benchmarks in terms of speed, sensitivity and ease of integration. The LEA-5 GPS module series is based on the company’s fifth generation positioning engine, u-blox 5, which boasts an acquisition performance of less than one second. These versatile, stand-alone GPS receivers combine an extensive array of features with flexible connectivity options. Their ease of integration results in fast times-to-market for a wide range of automotive, consumer and industrial applications with strict size and cost requirements. Further, this new generation is backwards compatible and suited for use in mass market GPS-enabled consumer devices. The LEA-5 GPS module series is lead free and has an industrial temperature range of -40 to 85 °C. Its small form factor and SMT pads allow for fully automatic assembly processes with standard pickand-place equipment and reflow soldering. The LEA-5H GPS module comes with a Flash EPROM that enables easy firmware upgrades and set-up configuration saving options. The ROM-based LEA-5S offers further cost efficiencies. Both modules feature the company’s OMA SUPL compliant A-GPS interface and support AssistNow Online and AssistNow Offline A-GPS services. www.mwee.com/204201704 ensures an easy migration from LEA-4 module designs, with even better performance and improved cost-efficiency. The u-blox 5 offers an ultrafast acquisition time thanks to its 50-channel GPS architecture with over 1 million correlators and separate acquisition and tracking engines, capable of massively parallel searches. Combined with the company’s AssistNow A-GPS service, the the fifth generation chip and module acquires satellites in less than one second. LEA-5 modules also boast an impressive -160 dBm acquisition and tracking sensitivity. These features, added to the module’s small size and low cost make them ideally Secure microcontroller designed to protect mobile payment and TV Atmel Corporation has introduced the AT91SC464384RCU, the latest addition to the AT91SC Advanced Telecoms product family. Based on the ARM® SC100, this secure microcontroller targets mobile payment and mobile TV applications. It features a compact onchip ROM program memory of 464 KB, a flexible 384 KB EEPROM for data, and 18 KB of RAM. Communication interfaces are ISO7816 and Single Wire Protocol (SWP). The mobile telecoms environment is moving towards the convergence of the wireless, internet, contactless and TV broadcasting worlds. Consequently, through the adoption of new technologies such as NFC, TCP/IP and Smartcard Web Server, the smart card’s responsibility is Compact DVB-H external antennas deliver high performance and durability Pulse has introduced an external Digital Video Broadcast-Handheld (DVBH) planar printed wire board (PWB) antenna, designated W3520. Thin and compact, the antenna is fully tested and matched for easy installation into DVB devices to enable fast product development cycles and ramp-ups. W3520 measures 50.5 mm (long) x 10.5 mm (wide) x 3.0 mm (high). The antenna operates at a frequency range of 470 to 750 MHz with a maximum 3D gain of minus 4.5 dBi at 470 MHz and minus 3.5 dBi at 750 MHz, with a minimum return loss of minus 3 dB. This exceeds the Mobile and Portable DVBT/H Radio Access Interface (MBRAI) specifications by a margin of 4 dB, ensuring high performance with minimal signal loss. Pulse’s W3520 antenna has a micro-miniature connector interface (MMCX), the coaxial RF connector standard for wireless devices, and integrated circuits. Easy, snap-in installation requires no special RF training or expertise. It has 360 degrees of rotation, an impedance of 50 Ohms, and operating temperatures ranging from -40 to +85 degrees Celsius. The W3520’s very short, rigid connector features mechanical durability that can withstand most twisting and bending without breaking. While most antennas of this type are either whip antennas with a long wire or retractable antennas that work only in the extended position, the W3520 DVB-H gives excellent performance in a smaller size. www.mwee.com/20420744 increasing and is becoming a key and individual security element within this complex environment. This micocontroller, offers the ability to secure highly sensitive digital transactions. The device, with its highend security features, targets Common Criteria EAL4+ certification, thereby ensuring total security for mobile TV and mobile payment applications. www.mwee.com/204201721 Microwave Engineering Europe ● December 2007 ● www.mwee.com 036_MWEE.indd Sec1:36 23/11/07 10:54:27 http://www.mwee.com/204201704 http://www.mwee.com/20420744 http://www.mwee.com/204201721 http://www.mwee.com
