Doherty amplifiers debut at European Microwave Week
Innovative RF power products and experts in high-power RF design will be on hand to demonstrate the capabilities of the complete Ampleon product line-up at European Microwave Week 2017 in Nuremberg (Oct 8-12). The company will also present technical papers in various sessions.
RS Components to sponsor open source design conference
RS Components (RS) is sponsoring ORConf, an open source digital design and embedded systems conference that covers from the transistor level up to Linux user space and beyond — featuring presentations and discussion on free and open source IP projects, implementations on FPGA and in silicon, verification, EDA tools, licensing and embedded software.
250W device powers up 50V GaN HEMT family
Global supplier of GaN-on-SiC high electron mobility transistors (HEMTs) and monolithic microwave integrated circuits (MMICs) with best-in-class reliability, Wolfspeed, has extended its family of 50V GaN HEMT RF power devices by adding a 250W part with a frequency range up to 3.0GHz and the highest efficiency of any comparably-rated GaN device available.
Cool designs for miniaturised high-power applications
Some major concerns for modern electronic applications include miniaturisation and increasing power densities. The lifetime of electronic applications can be dramatically reduced by the increase of the working temperatures by just a few degrees. Further, the insulation of the whole printed circuit board (PCB) from the environment in order to provide efficient protection against humidity and dust for certain applications turns heat dissipation an ...
Use circuit models to chart power device thermal parameters
Higher power levels are being handled in smaller spaces meaning that remaining losses are concentrated in the same small area or volume. Thermal considerations can be the critical path to a successful design, says Kim Mosley, Vicor
Applications are changing with the times so why aren't batteries?
Human beings are definitely creatures of habit. This is especially the case when it comes to buying consumables like batteries.We know batteries are important but we continue to buy cheap, subpar batteries that run out too quickly and simply cannot handle the heat.Michele Windsor, Global Marketing Manager for battery specialist Ultralife Corporation, explains the demands that three essential applications place on the humble 9V battery.
Industrial-strength MCUs tackle complex IoT applications
With the introduction of industrial-strength microcontrollers (MCUs) delivering higher performance, more features and lower power, Silicon Labs has expanded its energy-friendly EFM32 Gecko portfolio. The new EFM32GG11 Giant Gecko MCU family offers a wide feature set for the low-power MCU market, targeting smart metering, asset tracking, industrial/building automation, wearables and personal medical applications.
Record-breaking graphene has ten billion carbon atoms
Each atomic layer thin, tear-resistant, and stable. Graphene is seen as the material of the future. It is ideal for e.g. producing ultra-light electronics or highly stable mechanical components. But the wafer-thin carbon layers are difficult to produce. At the Technical University of Munich (TUM), Jürgen Kraus has manufactured self-supporting graphene membranes, and at the same time systematically investigated and optimised the growth of the...
Simplify your simulated GaN designs with LTSpice model
Prior to building hardware, power system design engineers want to be fast, accurate and confident with their simulated designs. Achieving these goals with GaN designs has become easier with GaN Systems’ new set of LTSpice models. Increasing efficiency and power density requires proper layout and understanding of the characteristics of these fast transistors.
DC/DC converters for next-gen SiC MOSFETs
The main challenges of driving SiC MOSFETs include high-frequency and high-voltage switching.Extreme voltage potentials between the control and power side can wear down isolation barriers and lead to failures. To meet these tough requirements, RECOM has recently introduced a new 2W DC/DC converter series specially designed to power the latest generation of SiC MOSFETs.Switching SiC MOSFETs requires turn-on and turn-off voltages atypical of other ...
