White Paper: Wideband 400W Pulsed Power GaN HEMT Amplifiers
Date: December 1, 2010
The high power and wide bandwidth potential of GaN HEMT devices is well known. Such wide bandwidth is essential for next-generation frequency-agile software-defined radio architectures supporting multiple frequency bands and various standards. This paper presents 400W pulsed power amplifiers operating in the 2.9GHz to 3.5GHz band in high power pulsed radars. These amplifiers could be used for 3.5GHz WiMAX infrastructure applications, as they can support high peak-to-average digitally modulated signals while providing good linearity.
