Abstract: Meeting the power, efficiency and linearity requirements of modern-day RF systems continues to become ever more challenging. In particular, GaN devices offer unique advantages and thus are becoming ubiquitous in high-power RF systems. However, they also present challenges with regard to transient response and linearization that complicate both device and circuit design. In this presentation we discuss a comprehensive approach to RF device, circuit and component design. We have realized improved results and shorter development cycle time by utilizing a rigorous approach including physical modeling, compact modeling, and behavioral modeling from the device level up to the system level. We see improved accuracy in design and simulation by using test signals that better represent real life situations. Industry standard test signals are used in conjunction with transient-capable behavioral models for both system level characterization and simulation of devices and circuits. By utilizing a more comprehensive and application-oriented approach, we can realize more accurate simulations during design and reduce the overall design cycle time.
