Effects Of Impedance Matching And Switch Quality On RF Test System Performance

This article from National Instruments defines characteristic impedance and the importance of impedance matching in RF switch systems. Impedance matching is designing an RF system so that all the source, load, and characteristic impedances match, in order to ensure maximum power transfer and minimum reflected power. The article also elaborates on design considerations for switch products and networks to improve impedance matching in switch systems and minimize signal reflections and power loss.
