In building a strategy for effective integrated-circuit design, it is important to understand the characteristics of different printed phase shifters. Optimization of the printed phase shifter design process can reduce unnecessary costs and design iterations, thus allowing designers time to improve the quality of the product. The design process includes various stages from analysis of requirements to final design documentation, balancing and trading-off factors such as electrical performance, size, cost, etc. In this article we consider design strategy of switched-line PIN-diode phase shifters.
