RUGGED NOTEBOOK COMPUTER
General Dynamics Itronix announced the GD6000 rugged notebook for the law-enforcement market. Based on the company's GoBook VR-2, the new notebook has been optimized specifically for in-vehicle applications. It weighs 6.2 pounds and meets the MIL-STD 810F standard for temperature range, vibration resistance, dust protection and humidity. In addition, its shell includes reinforced hinges to protect against vibration when an officer is involved in a high-speed vehicle pursuit.
The notebook has an Intel Core 2 Duo T9400 processor, a 120 GB hard drive and 4 GB of memory. It also includes integrated GPS and wireless connectivity (Wi-Fi, cellular data and Bluetooth). An embedded module supports data encryption, while optional software lets users, via a subscription service, remotely erase data on the computer or lock its contents if it's lost or stolen. The notebook starts at approximately $3495. — MARY ROSE ROBERTSwww.gd-itronix.com
Avago Technologies, a supplier of interface components for communications applications, unveiled a Band 8 WCDMA duplexer. The ACMD-7605 offers 1.3 dB typical Tx insertion loss and 3.5 dB maximum IL over-temperature, which significantly lowers power consumption and improves talk time, according to the company. It also offers over-temperature isolation performance of 51 dB minimum in the Tx band and 48 dB minimum in the Rx band.
