Broadband power amplifiers are becoming increasingly important for communications and radar phased array applications. Amplifying concurrent signals allows for increased data through-put with carrier aggregation and improved radar tracking performance, among other benefits. However, non-concurrent broadband amplifier design is limited in performance by fundamental matching limitations, and suffers further in the concurrent mode due to signal mixing.To reduce the cost of phased arrays, a low-cost GaN-on-Si technology is first investigated on which broadband power amplifiers are designed and fabricated. Various passive structures are simulated to validate process stack-up simplifications, along with the design and characterization of a narrowband proof-of-concept X-band power amplifier. Fundamental limitations are summarized and utilized to develop a design procedure for multi-stage power amplifiers with increased gain for phased array applications. This procedure is confirmed with a fabricated matching network. These results are then used in dual-band and broadband power amplifiers designs, which are fabricated with commercially available GaAs and GaN technologies. Hybrid and MMIC implementations in both cover 2-18 GHz in aggregate.The power amplifier characterization focuses on comparing each implementation in the non-concurrent and concurrent mode to understand the effect each power amplifier has on signal amplification. A new broadband power amplifier architecture is developed to improve the performance of broadband power amplifier amplifying concurrent signals. Results indicate that a PA with this architecture can achieve similar power and efficiency as compared to a standard broadband PA, whereas linearity can be improved and/or simplified using this approach.
