Integra Technologies had announced a matched, GaN-on-SiC transistor, offering 50W at 5-6GHz. Designed for pulsed C-Band Radar applications, the IGT5259L50 HEMT is matched to 50Ω and supplies 50W peak pulsed power at 50V drain bias. Actual range is 5.2-5.9GHz with instantaneous response, and 14dB of gain is available at 43% efficiency (1ms/15% pulse). It comes in a 20x11mm RoHS-compatible metal-ceramic ...

Military personnel have come to rely in reliable wearable devices and for reliability, the design of the battery pack is critical. Jonathan DiGiacomandrea explains how technological advances are influencing the design of batteries in military devices. The global demand for connected devices is growing, with trends such as the internet of things (IoT) and home automation setting certain expectations from users. ...

Charcroft Electronics has published a new linecard representing its specialisation in the design-in and sourcing of COTS, high-reliability and sector-approved components. Likely to be most relevant for avionics, high-end audio, defence, oil and gas, rail and space sectors, the line-card covers passives, electromechanical, opto-electronics, RF and microwave components, as well as magnetics, power supplies, sensors and high-reliability semiconductors. The linecard ...

Harwin has introduced of a female contact for its 2mm-pitch Datamate connectors that boost current delivery to 8.5A. It uses a proprietary six-finger design, machined from a single piece of beryllium copper. “The innovative patented design employed in these components presents more contact points, which enhances resilience to shock and vibrational forces,” said the firm – ratings are 100gravity and ...

This award goes to the best design, manufacturing or distribution company that set up operations in Europe in the past five years. Winner Spacechips Taking the title this ...

4G LTE mobile communications could transform in-flight connectivity and there is no reason why it can’t happen, says ip.access, the London-based small cell supplier. The firm has presented an argument for aviation companies to provide cellular coverage to its passengers. It outlines the value of deploying small cells to improve the efficiency of in-flight connectivity with cellular coverage. According to ip.access, ...

Coilcraft’s has introduced a series of current sense transformers, operating up to 40A over 400Hz to 1MHz, and offering 4,000Vrms isolation voltage between the sense and output windings, using insulation reinforced to UL 60950-1. To minimise power loss, the resistance of the sense coil is very low: 840μΩ in all versions of the series, dubbed CST2020. Available in four turns ratios ...

Green Hills Software is to verify conformance of its Integrity-178 operating system with the technical standard for Future Airborne Capability Environment (FACE) edition 2.1. Certon, the critical systems certification firm, will help carry out the verification Time-Variant Unified Multi Processing (tuMP) operating system for three different multicore architectures, or Units of Conformance (UoC): Intel, ARMv8 and PowerPC/QorIQ. Integrity-178 is also being verified ...

Aerospace electronics demand higher standards of reliability for their thermal design than other industries, writes Tom Gregory of 6SigmaET.

Connector and cable technology is being transformed to meet new requirements as military systems improve
