R&S expands mid-range spectrum analysis to 44 GHz

R&S has launched the 44-GHz FPL1044 spectrum analyzer along with a 40-MHz real-time spectrum analysis (RTSA) option for the entire FPL family. With the RTSA option, the FPL1044 can perform real-time measurements across its full frequency…

GaN transistor cuts losses and heat

EPC’s first Gen 7 eGaN power transistor, the 40-V EPC2366, delivers up to 3× better performance than equivalent silicon MOSFETs. Now entering mass production, the device features a typical RDS(ON) of 0.84 mΩ and an optimized RDS(ON) ×…

High-density power module fits compact AI servers

Enabling higher power delivery within the same rack space, Microchip’s MCPF1525 power module delivers up to 25 A per device and can be stacked to 200 A. The module integrates a 16-VIN buck converter with programmable PMBus and I²C control,…

Vishay shrinks inductors, keeps full performance

Four power inductors in 0806 and 1210 case sizes from Vishay offer improved performance for commercial and automotive applications. Compared to competing inductors with similar performance, the devices use considerably less board space—up…

Added-conductor and directional audio interconnects: Real-life benefits?

Does vendor-claimed audio cable directionality make theoretical sense, far from delivering real-life perceptible benefit? And what about the number and organization of in-cable conductors? Within my recently published two-part series on the…

Designing energy-efficient AI chips: Why power must be an early consideration

AI’s demand for compute is rapidly outpacing current power infrastructure. According to Goldman Sachs Global Institute, upcoming server designs will push this even further, requiring enough electricity to power over 1,000 homes in a space…

Classic constant current cascode

An important figure of merit for all precision constant current sources is their active impedance.  Which is to say, just how “constant” is their output held against changes in applied voltage?  Frequent and expert Design Idea (DI) commentator…

Silicon coupled with open development platforms drives context-aware edge AI

Edge AI reached an inflection point in 2025. What had long been demonstrated in controlled pilots—local inference, reduced latency, and improved system autonomy—began to transition into scalable, production-ready deployments across industrial…

EDN announces Product of the Year Awards

EDN has announced the winners of the annual Electronic Products Product of the Year Awards. Now in its 50th year, EDN editors looked at over 100 products across 13 component categories to select the best new components. These categories include…

EDN announces winners of the 2025 Product of the Year Awards

The annual awards, now in its 50th year, recognizes outstanding products that represent any of the following qualities: a significant advancement in a technology or its application, an exceptionally innovative design, a substantial achievement…

Short push, long push for sequential operation of multiple power supplies

Industrial systems normally use both analog and digital circuits. While digital circuits include microcontrollers that operate at 5 VDC, analog circuits operate generally at either 12 or 15 VDC. In some systems, it may be necessary to switch…

Why power delivery is becoming the limiting factor for AI

The sheer amount of power needed to support the expansion of artificial intelligence (AI) is unprecedented. Goldman Sachs Research suggests that AI alone will drive a 165% increase in data center power demand by 2030. While power demands continue…
