Tried and true strategies for speeding up InP HEMTs are clarifying the path to extending the bandwidth of their GaN cousins to millimeter-wave frequencies. Progress was realized by switching from AlGaN and GaN to an AlInN and GaN heterostructure according to Colombo Bolognesi from ETH-Zürich and Nicolas Grandjean from EPFL.


Since the late 1990s Integra has been manufacturing pulsed, S-band silicon transistors for radar. It has recently expanded its portfolio with GaN versions that are smaller, more efficient, and deliver gain over a far broader bandwidth. Richard Stevenson reports.


GaN power devices are smaller and more efficient than equivalents made from silicon. But significant commercial success will only follow when their manufacturing costs fall, a goal that can be realized with production on 150 mm silicon CMOS writes Michael Briere on behalf of International Rectifier.


The 2.2 kW static induction transistor developed by Microsemi is destined for success. It allows UHF radar manufacturers to build systems with far fewer components, say the company’s Mike Mallinger, Bruce Odekirk, Mar Caballero and Francis Chai.


The battles in the solar industry sees companies compete for market share as well as touting their technology as the answer to industry challenges. How does the technology stand up under scrutiny. St. J. Dixon-Warren and Tim White of Chipworks discuss their findings when they looked under the hood of CIGS Solar Panels.


Richard Stevenson looks at the latest research occuring in the compound semiconductor industry.
