50 GHz Handheld Combination Analyzer

Keysight Technologies, Inc. (Santa Rosa, CA) has added six millimeter-wave models to its family of FieldFox handheld analyzers. The flagship model is the industry’s first handheld combination analyzer to provide coverage to 50 GHz. Three combination-analyzer models cover 32, 44 or 50 GHz and provide spectrum analysis, vector network analysis, and cable and antenna testing in a rugged, portable unit. The three spectrum analyzer models cover the same frequency range.

31–36 GHz Receiver

Richardson RFPD (Geneva, IL), Inc. announced the availability and full design support capabilities for a new receiver from M/A-COM Technology Solutions. The XR1020-QH is a 31–36 GHz receiver with a noise figure of 3 dB and 14 dB conversion gain. It integrates a low noise amplifier, image reject mixer and LO buffer amplifier within a fully-molded, lead-free, 4-millimeter, 24-lead PQFN package. The image reject mixer eliminates the need for a bandpass filter after the LNA to remove thermal noise at the image frequency. I and Q mixer outputs are provided, and an external 90° hybrid is required to select the desired sideband. The XR1020-QH is suitable for point-to-point radio, SATCOM and military applications.

12A POL DC-DC Converters

TDK Corporation (National City, CA) has introduced the 12 Ampere TDKLambda iCH series of POL (Point of Load) non-isolated DCDC converters. Accepting a wide range input of 4.5 to 14 VDC, the series can operate from either a 5 VDC or 12 VDC bus. The iCH series can provide output voltages from 0.7 to 8.5V, with efficiencies of up to 97%. A low internal power loss allows the iCH to deliver 12A output current, without forced air cooling, in ambient temperatures in excess of 70 °C.

AdvancedTCA Chassis

Pixus Technologies (Waterloo, Ontario, Canada) now offers a 15U AdvancedTCA (ATCA) chassis that exceeds 400W/slot cooling capability and meets stringent NEBS requirements. The Pixus chassis leverages the original Kaparel design that used patented Ri- Cool II blowers for 275W/slot of cooling. Today’s 15U unit provides more air evacuation using the next generation of reverse impellar hot-plug cartridges. The new RiCool III blowers feature 185 CFM of airflow per fan with 71mm H20 of static pressure.

Quantitative Diagnostics of Multilayered Composite Structures with Ultrasonic Guided Waves

This nondestructive methodology inspects a sound-absorbing composite structural system consisting of polymeric and metallic materials.

Aging infrastructure has a major impact on safety, increasing the need to assess damage severity. Machinery, systems, and components such as airplanes, cars, pumps, and pipes in the oil and chemical industry are subject to varying cyclic service loading and environmental influences. Sometimes multilayered coatings are used, requiring a high-resolution inspection to confirm the presence of a defect such as a delamination, and accurately locate and quantify its size. Highly attenuating materials may significantly increase the inspection time while limiting defect observability. Guided waves have been recognized as having excellent potential for nondestructive inspection. However, the presence of viscoelastic coatings used for corrosion protection is one of the major obstacles for guided wave inspection.
