ELECTRONICS: Cree Inc. announces the sample release of two new GaN HEMT transistors, expanding the power range and addressable applications of the Cree product family.
The CGH40006P is ideal for driver and medium power stages within broadband amplifier topologies. In addition, it can be used in low-noise amplifier applications where the superior ruggedness of GaN HEMTs can lessen the need for protection components, typically required in GaAs MESFET low-noise amplifiers.
A demonstration amplifier using the new transistor, at 28V, provided a 2 to 6 GHz instantaneous bandwidth achieving 12 dB average small signal gain and 8W typical saturated output power at greater than 50 percent drain efficiency over the entire band.
Cree has also introduced the CGH31240F, which is a high-power, class A/B S-Band GaN HEMT transistor. It is an internally matched 240W packaged device for the 2.7 to 3.1 GHz band. It is designed for civil radar applications such as weather and air traffic control, as well as for marine radar. The CGH31240F, operating at 28V, offers more than 10 dB power gain while providing more than 240W saturated power with greater than 50 percent power added efficiency using a 300 µsec, 10 percent duty cycle pulsed signal.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
