How do the military and aerospace use MBSE?
Model-based systems engineering (MBSE) is broadly defined as the structured use of digital modeling to support system features, requirements, design, verification, and validation extending from the conceptual design phase and continuing until end of life. The concept of systems engineering is deeply engrained in the military and aerospace communities. MBSE represents a shift from highly […]
High-gain GaN amps handle L-band applications
Qorvo introduced the highest gain 100-watt L-band (1.2-1.4 GHz) compact solution: a GaN-on-SiC power amplifier module (PAM) targeting commercial and defense radar applications. The QPA2511 GaN-on-SiC PAM includes an integrated two-stage amplifier solution offering 60% power added efficiency in a circuit size 70% smaller than equivalent two-stage solutions. This unparalleled performance significantly reduces overall system power […]
What can you make with MEMS technology?
Microelectromechanical systems (MEMS) has several names, including micro-electro-mechanical systems, and micromechatronic systems. In Japan, MEMS is called micromachines, while in Europe, it’s referred to as microsystem technology (MST). Whatever name that’s used, MEMS devices are made using components measuring from 1 to 100 μm (0.001 to 0.1 mm), with MEMS devices ranging from 20 μm […]
Automotive grade thick-film chip resistors offer anti-sulfur performance
Many types of electronic products across a variety of market segments require higher reliability components. Automotive grade resistors offer increased reliability and improved performance without the high cost and limited availability of components procured to established reliability military specifications. Stackpole’s RMCA series is AEC-Q200 qualified and provides excellent long-term reliability. This series is produced on […]
Radiation tolerant 20-GHz SPDT absorptive RF switch targets space applications
Teledyne e2v HiRel announces the availability of a rad-tolerant 20 GHz, Single Pole Double Throw (SPDT) absorptive RF switch, model TDSW020A2T, that is ideal for use in demanding high reliability, space and defense applications and is now available with qualified material off-the-shelf. This new RF switch, developed on 0.15 μm InGaAs pHEMT technology, will be available […]
Super-high energy density film capacitors save space and weight
Exxelia introduced Miniature Micro-Layer (MML) capacitors, a breakthrough technology that allows tremendous size and weight reduction thanks to an unrivaled energy density. The energy density of 400 J/dm3 allows for a reduction in size and weight compared to traditional Polypropylene or Polyester dielectrics, together with an increased operating temperature up to 140°C and transient voltage […]
Chip resistors are AEC qualified
Electronics that require high reliability are no longer confined to military, aerospace, medical, or automotive market sectors. Many types of electronic end products now demand the higher reliability provided by automotive-grade resistors. Automotive-grade resistors offer increased reliability without the high cost of established reliability Mil-Standard products which allows engineers to increase the reliability of their […]
Optical links for spacecraft, Part 2: Projects and progress
Using laser-sourced light beams rather than wireless RF to link spacecraft with Earth offers the possibility of a significant increase in data rates. Still, there are significant technical challenges to the concept. The previous part of the article established the need for higher-speed data links to spacecraft and their missions and looked at some of […]
Optical links for spacecraft, Part 1: The throughput limitation
Using laser-sourced light beams rather than wireless RF to link spacecraft with Earth offers the possibility of a significant increase in data rates. Still, there are significant technical challenges to the concept. Scientists, engineers, and researchers communicating with spacecraft have a problem: there’s so much data coming from these spacecraft – and to send to […]
