Voltage Controlled Oscillator

Crystek's (Fort Meyers, FL) CVCO55CC-3850-3850 VCO (Voltage Controlled Oscillator) operates at 3850 MHz with a control voltage range of 0.5V~4.5V. This VCO features a typical phase noise of -110 dBc/Hz @ 10KHz offset and has excellent linearity. Output power is typically +7 dBm. Engineered and manufactured in the USA, the model CVCO55CC-3850-3850 is packaged in the industry-standard 0.5-in. x 0.5-in. SMD package. Input voltage is 8V, with a max. current consumption of 35 mA. Pulling and Pushing are minimized to 1 MHz and 0.2 MHz/V, respectively. Second harmonic suppression is -15 dBc typical.

USB Thermocouple Power Sensors

Agilent Technologies Inc. (Santa Clara, CA) has announced the addition of two new models to its U8480 Series USB thermocouple power sensors. The U8480 Series now includes an expanded frequency range to 67 GHz and a measurement speed of 900 readings/second. The U8480 Series’ real-time measurement uncertainty feature, the first of its kind in the industry, significantly reduces overall test time by removing the need for time-consuming manual measurement uncertainty (MU) calculations. Users can now compute MU in real time and at any given point. The feature also allows them to display power measurements and their MU simultaneously.

Canadian researchers employ recycled carbon-fiber mats to produce thermoset composites

Carbon-fiber-reinforced thermoset composites continue to be difficult to recycle, as they are a complex mixture of different materials such as thermosetting polymers, carbon fibers, and fillers. Researchers from the Universite Du Quebec at Montreal, Bell Helicopter Textron Canada, and the National Research Council Canada investigated using carded recycled carbon-fiber mats and epoxy resin to fabricate thermoset composite plates.

Heated air technology helps optimize CFRP assembly

Assembly of large and complex carbon-fiber-reinforced plastic (CFRP) components requires the use of liquid resin-based materials for applications such as shimming and aerodynamic sealing. These materials generally require curing times up to 12 h; heated air technology can reduce that time to 2 h. Read more at http://articles.sae.org/12510.

Signal AHPEC Platform

GE Intelligent Platforms (Waltham, MA) has announced the DSP281, a rugged, dual-node, quad-core 6U OpenVPX High Performance Embedded Computing (HPEC) deployed server platform. GE’s HPEC architecture scales from one to many processor nodes per enclosure via RDMA-enabled InfiniBand® and Ethernet dual port network interface cards. In addition, system integrators can minimize card count by mapping multiple platform functions, such as control, DSP, image and video processing and graphics, onto one or more DSP281s.

Upmast Radar System

Kelvin Hughes (Enfield, UK) offers a carbon composite housing for its SharpEye™ radar system. With coherent transmission and Doppler processing, the system separates targets from clutter, resulting in greatly improved situational awareness, even in adverse weather conditions. A lightweight antenna turning unit and transceiver housing is resistant to shock, vibration, and corrosion. The technology also features a low Radar Cross Section (RCS) design and a GaN-transistor Transceiver.

Inductance-to-Digital Converter

Texas Instruments (Dallas, TX) unveiled an inductance-to-digital converter (LDC), a new data converter category that uses coils and springs as inductive sensors. Inductive sensing measures the position, motion, or composition of a metal or conductive target, as well as detects the compression, extension or twist of a spring.
