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 […]

How do SysML and model-based design relate to MBSE?
Model based design (MBD) is not a new concept; it’s been successfully applied to complex software systems for many years. MBD is often implemented using the unified modeling language (UML) for software development from the Object Management Group (OMG). Extending the concepts of MBD to cyber-physical systems, including both software and hardware, is a relatively […]
Tantalum capacitors meet MIL-PRF-39006 specs
Exxelia is expanding its line of MIL-PRF-39006/22 & MIL-PRF-39006/25 tantalum capacitors, with the support of the reliability level R. Exxelia now offers the reliability level R, in addition to levels M and P for the specifications MIL-PRF-39006/22 & MIL-PRF-39006/25, equivalent to CLR79 and CLR81 series. Available in all package sizes (T1 to T4), these fully sealed products […]
Anti-sulfur thick film chip resistors feature working voltage up to 75 V
Sulfur contamination for thick film resistors is becoming a more prominent issue for a wide range of end products. Electronic devices and circuitry may encounter sulfur in the presence of oils, lubricants, gaskets, hoses, and atmospheric gasses in highly industrial areas. Finding anti-sulfur resistors can be challenging and finding them with the ideal power and […]
Miniature reed relays boast low RF losses and low insertion loss
Pickering Electronics has launched a new miniature coaxial reed relays for high-frequency RF systems up to 3GHz. Series 113RF SIL/SIP reed relays feature a 2mm spacing footprint, enabling them to be stacked at very high densities. Series 113RF reed relays are suitable for switching up to 10W, 0.5A. 1 Form A configurations (SPST normally open) are […]
How do digital threads & digital twins fit in MBSE?
Digital threads and digital twins are used to create the virtual environments needed to implement model-based system engineering (MBSE), especially for complex cyber-physical systems. Digital threads are complete records of all details of specific aspects of product definition, development, and deployment, from conception through end of life. A digital twin is a comprehensive virtual representation […]
What’s MBSE and what does it mean for designers?
Model based system engineering (MBSE) uses digital twins, digital threads, and domain models to replace document-based information exchanges during the system development process. It is widely used with complex cyber-physical systems in aerospace, energy, healthcare, and transportation to define features, design, analyze and validate a system using virtual tools. For designers, MBSE is an expansive […]
Chip sockets handle flat no-lead SO-8 packages
A new high-performance elastomer socket for 1.27-mm-pitch QFN packages called the SG-MLF-7103 socket is designed for a 6.15×5.15-mm package size and operates at bandwidths up to 30 GHz with less than 1 dB of insertion loss (GSSG configuration). The contact resistance is typically 20 mΩ/pin. Network analyzer reflection measurements for the G-S-S-G case were taken […]
Signal relays offer max switching currents of 2 A or 3 A
CUI Devices announced the first launch from their Relays Group with the introduction of a new line of signal relays. Ideal for low-level current switching in industrial applications, security devices, and test and measurement equipment, CUI Devices’ signal relays offer max switching currents of 2 A or 3 A in SPDT (1 Form C) or DPDT (2 […]
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 […]
