Syfte och mål

The goal of this project is to improve cost- and energy efficiency of 5G wireless communication transmitters through investigation of novel integrated active antenna concepts. The proposed project targets a complete proof-of-concept of IADAT = Integrated Active Doherty Antenna Transmitter, including in-depth understanding of its fundamentals and experimental verification of its key principles through a small-scale testbed. This also includes suitable packaging and filtering solutions.

Resultat och förväntade effekter

1: Understanding of antenna-PA integration fundamentals by answering the following questions: Taking the IADAT solution as the starting point, what are the key design parameters and what are fundamental limits when used in MIMO arrays? What are the integration scaling laws? 2: Established multi-disciplinary design flow for deep integration active antennas; an optimum antenna element design. 3: Identified suitable packaging and filtering solutions for Doherty architectures. 4: Experimental demonstration of the IADAT concept
