The article focuses on a research conducted on the use of radar technology such as gallium-nitride (GaN) technology and high-speed converters in aerospace and defense companies. Various topics discussed include benefits of GaN technology, development of power amplifiers (PA) based on GaN and gate switching.

The article reports on the evolution of radar technology. It is said that radar systems are evolving into multiple-function platforms, along with active signal switching and smaller, more efficient antennas. Digital technology, modern data converters such as analog-to-digital converters and digital-to-analog converters have enhanced radar technology.

The article focuses on recent developments the radar systems. It mentions that the wide range of application of radar technologies has made several companies to develop their technologies and informs about electronically scanned array (AESA) technology on which the latest radar systems of Raytheon Co. and Northrop Grumman Corp. are based. It states that Lockheed Martin's latest radar its 360-degree scanning technology on the EQ-36 radar.

The article focuses on Towerjazz' announcement of new manufacturing technologies to cater the growing market for radar sensors. Comments of Marco Racanelli, senior vice president of the radio frequency (RF) and high performance analog business at Towerjazz regarding these technologies are also presented.

In this article, the author reports that many different approaches have been tried by radar system developers and integrators to compensate for some of the shortcomings of early high-frequency technologies over the years. The author also says that the engineering ideas that attempted to overcome such device limitations as frequency stability were both innovative and impressive in tracing the history of the development of early radar systems.
