Waveguide Mixer

Anritsu Company (Richardson, TX) has introduced the MA2806A High Performance Waveguide Mixer that can be integrated with its MS2830A Spectrum/Signal Analyzer to create a millimeter-wave (mmWave) measurement solution. When used with the MS2830A-044/045 models, the MA2806A supports spectrum mask measurements of the V band (50-75 GHz) to accurately determine characteristics of ultra-wideband signals. P1dB performance of better than 0 dBm as well as minimum sensitivity performance of -150 dBm/Hz (meas) can be achieved. Design, manufacture, and QA engineers can now measure extremely weak signals at V band frequencies that are typically missed by conventional measurement systems.

Precision Assembly of Systems on Surfaces (PASS)

Chemiresistors represent a powerful class of chemical sensors that can be readily integrated into any electrical system, can be miniaturized, are readily multiplexed, and take nearly zero-power to operate. One of the greatest limitations to these sensors is a lack of selectivity, which is the electronic equivalent of noise. Interference from large varying background signals, such as humidity, can compromise the sensor signal to a point where there is no useful data. To address this challenge, new ways to integrate molecular constructs into carbon nanotube compositions that produce enhanced selectivity to certain molecules or classes of molecules were investigated to increase the signal to noise level in chemical sensors.

Development of a Novel Electrospinning System with Automated Positioning and Control Software

Electrospinning is a nanofiber fabrication technique that has grown in popularity due to its potential in numerous biomedical applications. The process uses an electrical charge to draw ultrafine fibers from liquid polymer solution to form a non-woven fiber scaffold. The polymer fiber diameters can range from millimeters to as small as nanometers in scale.

Advanced Multifunctional Materials for High Speed Combatant Hulls

Currently small boat combatant design focuses primarily on speed and maneuverability. It would be advantageous to expand these capabilities to include reduced radar cross-section, and enhanced survivability to blast and ballistic threats for both the structure and warfighters.

Multifunctional Shear Pressed CNT Sheets for Strain Sensing and Composite Joint Toughening

The main goal of this work is to obtain a scientific understanding of the possibilities provided by, and the behavioral features of, a novel type high performance carbon nanotube (CNT) reinforced composite material incorporated in the interfaces of composite laminates and bonded joins with the following two purposes: (a) providing enhancement of the interlaminar fracture toughness and strength and (b) serving as a continuous strain monitoring sensor.

Turbine Flow Meters: Technology-of-Choice for Measuring Critical Fluid Flow Applications

The aerospace industry has some of the most difficult operating conditions imaginable. Sensors of all kinds used in this industry must stand up to the environment and be able to perform under harsh conditions, fit in extremely tight spaces, and have electronics that can compensate for variable conditions in order to provide precise, repeatable results.

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.
