A unit of Laird Performance Materials recently added the ability to protect foam absorbers from moisture and heat—making them suitable for use in all outdoor environments. Broadband and lightweight, foam absorbers offer military and aerospace design engineers a valuable alternative to elastomers when seeking to minimize signal interference from direct reflection. … [Read more...]
Review of Magnetic Effects Testing—DO-160 Section 15
The Issue From the beginning of aviation, knowledge of the aircraft direction during flight has been critical to locating destinations. The magnetic compass was used for centuries in shipping, and naturally, it was adopted for aircraft use. Without visible signposts or landmarks, direction relies on the compass to provide the necessary information. The compass aligns with the … [Read more...]

4KW S Band SSPA for Satcom Uplink
Empower’s model 2176 is a compact high power GaN on SiC solid state CW amplifier. Standing 27 inches tall, it’s less than half the size of the typical legacy uplink HPA’s that it replaces. The slightly broader band brings flexibility to transmit in either of the two uplink channels. Besides the dramatic size reduction, the upgrade from legacy design to a next generation SSPA … [Read more...]

The Emerging Threat of Tactical Electromagnetic Interference & its Spread into Non-Defense Sectors
During the last five years intentional electromagnetic interference (IEMI) has emerged as a credible and increasingly likely threat to commercial and defence facilities alike, with a potentially crippling cost to individual organizations of such a localized attack. Hollywood has long used electromagnetic interference (EMI) and electromagnetic pulse (EMP) phenomena as the de … [Read more...]
Review of MIL-STD-1275 Requirements
Introduction This may seem disassociated from the electromagnetic compatibility (EMC) theme of this publication but issues dealing with power quality and the qualification testing has a direct link to EMC. Frequently the EMC engineers and technicians are tasked taking care of the power quality, so I believe that reviews of these standards are appropriate. MIL-STD-1275 deals … [Read more...]
Review of Space Applications EMC Requirements
The Contract Having been a long-time manufacturer of oxygen concentrator equipment, when I saw an opportunity to bid on a job to provide an oxygen concentrator system (OCS) for a satellite project I jumped at the chance. The specifications were normal for this type of system and of course electromagnetic compatibility (EMC) requirements were included. Having experience with … [Read more...]
HEMP Protection Strategy for Power System’s Electronic Equipment
Annotation The issue of protecting electronic equipment from the electromagnetic pulse of a high-altitude nuclear explosion is very relevant and important for the power industry. Current knowledge about individual HEMP protection elements, their specifications and application features is very important, but, at the same time, limited to ensure efficient protection of power … [Read more...]
