Abstract
Provided herein are various enhancements for including selectable delay or phase shift lines in microwave radio frequency (RF) systems. One example includes RF switches coupled between an RF input and an RF output. A first tier of the RF switches is coupled through first RF delay lines that produce first selectable delays or phase shifts, and a second tier of the RF switches is coupled through second RF delay or phase shift lines that produce second selectable delays or phase shifts. Tier coupling RF switches couple the first tier and the second tier and establish a cascaded arrangement among outputs of the first tier and inputs of the second tier.
