25 Sep 13. L-3 TRL Technology is working with Avanti Communications to provide secure Ka-Band satellite services to government and military agencies that use L-3 TRL’s CATAPAN® encryption devices for direct high-speed connectivity. Coverage includes parts of Europe, the Middle East, the Caucasus region and Africa. Ideal for high-demand government and military operations that require unlimited data transfer at superfast speeds (up to 10 Mbps), the new Ka-Band offering provides secure, cost-effective network options for users with multiple transportable and/or fixed nodes. Numerous encrypted secure voice and data scenarios have been tested over the capability, under differing weather conditions, without any degradation in service. Options include transportable variants utilising highly portable antennas for rapid deployment and a fixed-site variant providing a cost-effective connection. Tailored uncontended packages are available, including dedicated bandwidth and occasional use packages. Shared contended bandwidth packages are also available. This allows the services to be configured to meet a user’s specific operational requirements.
“We are pleased to be working with Avanti in bringing secure satellite communications to numerous international defence and government agencies,” said Adrian Cunningham, L-3 TRL vice president and head of its National Security division. “The Ka-Band airtime services offer extremely cost-effective network options with the added benefit of uncontended or contended communications, allowing users to stay connected during all types of weather.”
Ka-Band is part of L-3 TRL’s CATAPAN Bundled Airtime Service packages, which are designed to work in conjunction with its CATAPAN government grade network encryption devices and COTS modem hardware to provide secure mobile communications. A number of “out-of-the-box” dedicated service packages are available to ensure the highest levels of security for individual operational requirements.
24 Sep 13. M/A-COM Technology Solutions Inc. announced the newest entry in its portfolio of GaN in Plastic packaged power products. Optimized for L-Band commercial air traffic control, military radar, and long range perimeter monitoring applications at 1.2 to 1.4 GHz, MACOM’s new 2-stage, fully matched GaN in Plastic power module scales to peak pulse power levels of 100W in a 14 x 24 mm package size – delivering twice the power of comparably sized competing products. MACOM’s new high gain GaN in Plastic power modules are the first and only GaN-based modules to support surface mount technology (SMT) assembly, providing significant cost and process advantages compared to ceramic-packaged flange-mount components. Delivering clear benefits in size, weight and power (SWaP) while enabling high volume manufacturing efficiency, MACOM’s new GaN power modules extend the performance attributes of its discrete GaN in Plastic power transistors and establish new standards for GaN module integration. Under pulsed conditions, these modules deliver output power greater than 90W, with 30 dB typical associated power gain and 58% typical power added efficiency. Supporting 50V operation and up to 3 ms pulse width/duration for improved time on target, MACOM’s GaN in Plastic power modules reduce overall power consumption and cooling requirements compared to existing options. The module features a Land Grid Array (LGA) pattern for enhanced thermal flow and “True SMT” assembly. All inputs and outputs are formed on the back of the module and include edge castellations for ease of assembly inspection. The module’s flexible design allows for gate and/or drain pulsing, and includes a gate voltage sense port for use in temperature compensation or pulse droop compensation. Leveraging sophisticated thermal management techniques to ensure high reliability, the calculated me
