Full RF Signal Chains from 0 Hz to 110 GHz

Analog Devices (ADI) has expanded its RF capabilities in the full signal chain, including companion products, in the full bandwidth from 0 Hz to 110 GHz.This white paper provides examples of the wider frequency spectrum covered by ADI, and explains that true DC is important. Off signal chain performance is also critical, and this paper shows how low-noise, high-stability control and power components are important to overall RF signal performance.

Putting FPGAs to Work in Software Radio Systems

Recently updated, this handbook reviews the latest FPGA technology and how it can be put to use in software radio systems. FPGAs offer significant advantages for implementing software radio functions such as digital downconverters and upconverters. These advantages include design flexibility, higher precision processing, lower power, and lower cost.

How to Avoid PCB Re-spins when IC’s Change or are Obsoleted

Working with printed circuit boards (PCBs) for sophisticated military, aerospace, or medical systems can be a frustrating – and expensive – exercise, particularly when the customer requests “a simple upgrade” or modification after the boards have been made or after deployment. Thanks to Murphy’s Law, these “simple upgrades” are never as simple as they should be. Aries has developed a unique solution that can save you from having to re-spin your PCB due to IC obsolescence or package change.

Linear Motors

Heidenhain (Schaumburg, IL) offers ETEL ILF and ILM series ironless high-speed linear motors for use in the semiconductor and electronics industry. The motors utilize an ironfree coil design for zero-attraction force between the carriage and the magnetic way. The ILF is a smallersized motor for very high dynamic and low-moving mass applications; the ILM is a more powerful version of the ILF, and has an option to be air-cooled to increase continuous force output. The ironless motors come in a variety of lengths and heights with different degrees of force, and share the same profile so that one is interchangeable with the other. The motors can reach speeds of up to 20 m/s and peak force of up to 2,500 N. They are designed for direct drive applications and offer no backlash, fewer parts, and require no maintenance.

Coupling

C-Flex Bearing Co. (Frankfort, NY) offers a Super Plastic torsional damping coupling that stabilizes high-precision systems by dampening transient torque variations. The patented design offers high-torque loads with zero backlash for positioning in industries such as medical, packaging, and semiconductor. The standard flexible coupling is made up of two high-strength aluminum ends with glass-impregnated polyamide flexures. They are available with both set screws and “No Mark” steel clamp bushings. English and metric versions are available. Bore sizes range from 0.125" to 1.25", and 4 mm to 32 mm. Lattice and servo styles are available in both the Super Plastic and all stainless steel versions.

Pyramid Micro-Electrofluidic-Spray Propulsion Thruster with Integrated Attitude and Thrust Vector Control

NASA’s Jet Propulsion Laboratory, Pasadena, California A micro-electrofluidic-spray propulsion (MEP) system was built on a micro scale, in which arrays of hundreds of nano-thrusters are etched on silicon wafers like ICs, only a centimeter on a side. Many dozens of these thruster chips can be arrayed to form a macro-thruster of finite and significant thrust. Approximately 300 centimeter-square, 100-micro-Newton micro-thrusters are arrayed in a square pyramidal structure. The pyramid is of shallow obliquity, with no more than 20° offset from the spacecraft face. This small angular offset is sufficient to provide thrust vector control (TVC) for the thruster.
