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...]
Rohde & Schwarz presents next generation test solutions for Bluetooth® Low Energy up to version 5.2
The Bluetooth Special Interest Group (Bluetooth SIG) adopted the first specifications for BLE 5.2 at the end of 2019. This initially concerns the new power control functions. Rohde & Schwarz has already integrated specified tests into the Bluetooth test software of its wireless testers in the R&S CMW platform. In addition, Bluetooth LE 5.2 will provide extended audio … [Read more...]
Preventing Impact of High-Altitude Electromagnetic Pulse on Power Transformers
Protection of a power system’s electrical equipment from a high-altitude (more than 30 km) nuclear explosion (HEMP) impact is a challenging issue, which until recently has not received proper attention. The fact is that HEMP does not affect people directly, while the electromagnetic pulse resulting from this explosion is a powerful devastating factor for the power grid’s … [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...]
