2016’s Best Practices for NPI and NPD Success

Smart companies know that well disciplined new product introduction (NPI) processes are critical to success. Yet, even these companies can suffer from NPI failure when important projects, policies, and guidelines are haphazardly managed as clumsy manual processes.

High-Performance MEMS IMU Solutions for Demanding Applications

For MEMS IMU applications where the inertial profile is complex and highly dynamic, there are a number of attributes to consider when evaluating capabilities. Evaluating these attributes early in the design cycle provides an advantage over chasing open-ended deliverables, like "as accurate as possible."

GSPS DACs Enable Ultra-Wide Bandwidth Applications

To meet the increasing capacity demand of mobile customers, the emerging E-band market requires wider bandwidth capabilities compared to traditional microwave backhaul wireless architectures. Due to increased capacity, 2-GHz E-band systems will be needed in the near future. This white paper covers the demands of current E-band point-to-point systems, and how Analog Devices’ high-speed digital-to-analog converters (DACs) provide the necessary bandwidth and sampling frequencies to support them.

Case Study: Vance & Hines Wireless Fuel Management System for Motorcycles

Vance & Hines has represented the gold standard for aftermarket motorcycle parts and accessories since 1979. The company's new Fuelpak FP3 is a cost-effective fuel management system that links with a user's smartphone to provide a more dynamic interface. "The smartphone integration gives us the ability to not only fix performance issues, but also enhance the rider experience," said Larry Hinds, manufacturing manager at Vance & Hines. "That meant the FP3 would utilize Bluetooth technology and more robust, complex PCBs."

CMOS-Compatible Ohmic Contact RF MEMS Switch

Lyndon B. Johnson Space Center, Houston, Texas Radio frequency (RF) microelectromechanical system (MEMS) switches have advantages over their solid-state counterparts. However, ohmic contact MEMS devices face several significant limitations, preventing entry into the mass market. These limitations are cost, reliability, packaging, and integration.

Miller-Jogging for Synthesizer Lock Algorithm Extension

NASA’s Jet Propulsion Laboratory, Pasadena, California The University of California Los Angeles (UCLA) has developed a wide range of CMOS (complementary metal–oxide–semiconductor) phase lock loop (PLL) chips with self-healing/self-calibration capabilities, allowing them to adapt, on the fly, to changes in temperature and other environment parameters. All CMOS PLLs typically have three major settings that self-healing and calibration can adjust: VCO (voltage controlled oscillator) coarse tuning, divider tuning, and CML (current mode logic) tuning. Previous work done at UCLA uses these “knobs” or settings exclusively to self-lock a PLL. Locking criteria is established by monitoring the control voltage with an analog-to-digital converter (ADC) to see if the PLL loop is settled in the middle of the range (locked), or sitting at the ground or supply (unlocked).

Deployable Antenna Circuit Board Material Design and Fabrication Process

This technology has applications in solar arrays for small satellites.The Integrated Solar Array and Reflectarray (ISARA) antenna requires a rugged circuit board material that will meet the following requirements: (1) remains sufficiently flat over the required operating temperature range with solar cells mounted, and under full solar illumination, including heat dissipation due to ≈30% efficiency solar cells; (2) provides a sufficiently high-quality RF-grade circuit board material needed to print the reflectarray antenna; (3) is sufficiently thin (<2.5 mm) to fit within the available stowage volume; and (4) has low mass density (≈5 kg/m2).
