Title:
STATE CHANGE STABILIZATION IN A PHASE SHIFTER/ATTENUATOR CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2016/209407
Kind Code:
A3
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.
