Abstract

An electronic system that includes a digitally selectable phase shifter circuit and an insertion loss fine adjustment circuit such that the system as a whole exhibits little or no change in insertion loss when changing phase state, and/or a digitally selectable attenuator circuit and a phase fine adjustment circuit such that the system as a whole exhibits little or no effect on phase when changing attenuation state. Included are methods for selecting adjustment control words for such circuits.
