As the adoption of solid-state devices in radar prove significant advances in system performance, Gallium Nitride (GaN), with its superior characteristics, has become the semiconductor of choice. While GaN offers tremendous gains in efficiency, there can be some challenges with high power pulse applications.
In this webinar, we define pulse-to-pulse phase stability and discuss its effects on a delay line canceller to reduce stationary clutter in MTI processing. We then explain sources of phase instability in GaN TRMs operating in “burst mode” and define phase stability metrics. Finally, we discuss phase noise and pulse stability measurements of GaN amplifiers.
