Qorvo, a leading global provider of connectivity and power solutions, has announced a compact, three-stage power solution for phased array commercial and defense radar.

Although the onus is not on the EMC test engineers and test laboratories to make the decisions on test levels, limits, and requirements, they are still required to identify test specifications and define test procedures, as well as perform the tests. 

Understanding antenna beamwidth and how it influences a test environment is critical to accurate and repeatable tests. This article defines antenna beamwidth, explores the antenna beamwidth properties, and explains its importance for compliance testing.

How do commercial UAVs differ from military UAVs for the electronic payload circuit designer who must choose the optimum printed-circuit-board (PCB) material for that mission?

Yttrium iron garnet (YIG) has an unusual property when used as a resonator, as its resonant properties do not depend on size but on the strength of the magnetic field passing through it. This has some downsides but also some major benefits.

NASA is adopting commercial-off-the-shelf (COTS) parts as an option for a variety of space applications and aims to create a consistent set of requirements to minimize risk and impact of part selection/usage on the performance of NASA spaceflight technology.

MtronPTI’s K-band diplexer, the UFDX9999-008, is one product of a broad portfolio of products that support Common Data Link (CDL) applications.

When sourcing power supplies for military and commercial applications, system design engineers must choose between commercial off-the-shelf (COTS) or custom products. This article clarifies the misunderstandings of each, including delivery timelines, ease of integration, and real-world performance.
