TL;DR: In this article, a 3D GaAs X-band PA MMIC with a very compact ultra-long delay line, and a multi-layer inductor is reported, and transmission line losses are measured.
Abstract: We report a 3D GaAs X-band PA MMIC delivering over two watts with excellent gain. Additionally, excellent performance is obtained from a very compact ultra-long delay line, and a multi-layer inductor. Transmission line losses are measured. This technology is attractive for Si also.

TL;DR: In this article, the authors report the development of an accurate closed-form model for 3D transmission line analysis and synthesis, and demonstrate the performance of a 3D 4-way Wilkinson divider.
Abstract: We report the development of an accurate closed-form model for 3D transmission line analysis and synthesis. Close agreement is observed between our model and full wave analysis. Additionally, we built and measured a number of 3D special elements. Excellent performance is obtained from a delay line, and a broadband coupler. A 3D 4-way Wilkinson divider design and measurement are presented. Transmission line losses are measured.
