Sometimes the best way of handling specialized power needs is through custom equipment optimized for the situation at hand. Alex Karapetian, Acopian Technical Co. Electronic system designers, engineers, program managers and original equipment manufacturers (OEMs) must address numerous challenges in the selection or development of an appropriate power supply for their systems. In some cases, […]
Sockets for BGA228 packages provide 52 GHz bandwidth
A new high-performance elastomer socket for 0.65-mm pitch BGA packages called the SG25-BGA-2045 socket is designed for a 11×11-mm package size and operates at bandwidths up to 52 GHz with less than 1 dB of insertion loss (GSSG configuration). The contact resistance is typically 20 mΩ per pin. Network analyzer reflection measurements for the G-S-S-G […]
Keysight Technologies, Samsung complete 5G interoperability tests
Keysight Technologies, Inc. says it has run successful inter-operability tests of its User Equipment (UE) Emulation Solution and Samsung’s new 5G base station based on 5G New Radio (NR) standards. Keysight and Samsung have agreed to align their plans to enable 5G base station testing and build an ecosystem of interoperable products. Combining Samsung’s product […]
Teardown: Leviton ground fault circuit interrupter
GFCIs detect hazardous current paths to ground and ground-to-neutral faults. A teardown reveals they are relatively simple but have circuit details that can be tricky to figure out. Bathrooms, kitchens, and other rooms with access to water are required to employ ac outlets with ground-fault circuit protection. GFCIs disconnect the output if they sense a […]
Samsung to use Anritsu signal analyzer for 5G System Development
Samsung Electronics Co., Ltd. will use the Anritsu MS2850A Signal Analyzer with 5G analysis software installed to support 5G system developments. Samsung unveiled its end-to-end 5G product portfolios, including 5G home routers (CPEs) and 5G Access Unit (AU), last year under development for commercial-grade products. The company is engaged with major operators in leading markets […]
High-temperature, harsh-environment tantalum capacitor technologies
Solid-tantalum capacitors have evolved with better design, construction, and testing methods to handle emerging requirements for harsh, high-temperature applications that put a premium on reliability. Chris Reynolds, AVX Corp. Wet tantalum capacitors are a proven, mature technology. They’ve long been employed in demanding, high-temperature applications because they have a variety of useful qualities. These include […]
Teardown: Inside the TP-Link Archer C7 wireless router
Here is what the architecture of modern-day dual-speed Ethernet/Wi-Fi router looks like these days. TP-Link’s Archer C7 dual-speed wireless router delivers 1,300 Mbps over the 5 GHz band and 450 Mbps over the 2.4 GHz band. That should be enough bandwidth for HD streaming, online gaming and other bandwidth-intensive tasks. The idea behind using two […]
APEC 2018 Industry Session to cover energy harvesting
At APEC 2018, the PSMA (Power Sources Manufacturers Association) Energy Harvesting Committee will host an Industry Session featuring six industry experts who will cover such topics as real-world applications, conditional monitoring, energy harvesting systems, PMICs (Power Management ICs) and low-power IoT (Internet of Things) devices. The Energy Harvesting Session (IS05) will be held on Tuesday, […]
Free simulation software uses stored data to help select components
The REDEXPERT free simulation software package now permits LEDs, varistors and PFC coils to be selected in a practice-oriented way on the basis of the measurement data stored in the system. The tool’s redesigned user interface allows developers to select electronic components quickly and precisely based on numerous parameters and filter options. REDEXPERT was launched […]
mm-Wave testbed helps validate first commercial 5G NR active array antennas at 26 GHz
Ball Aerospace and Anokiwave have validated the first commercial 5G NR active array antenna product designs in the 26 GHz band using the Keysight 5G NR-ready measurement testbed. The use of phased arrays at mmWave frequencies requires over-the-air (OTA) testing as well as spatial beam measurements. Keysight metrology-grade test equipment offers the sensitivity necessary to […]
