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...]
WAGO Updates Filter Modules for Marine Applications
WAGO has updated our filter modules to include built-in ground fault diagnostics. The 750-624/020-002 and 750-626/020-002 are able to monitor both the +24 VDC and 0 VDC supply connections for impedance to ground. The filter modules are perfect for marine applications. Engineers will design in a ground fault test device to detect error resistance to Earth in marine … [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...]
