Abstract :
This paper introduces a novel 30 GHz turnstile coupler design which is very compact, exhibits low losses and can be manufactured at low cost. The turnstile coupler is modular and allows the implementation of amplifiers as highly integrated millimeter wave power combiners. The achievable bandwidth is approximately 20%.
