Abstract

A system and method for the automated tuning of coupled resonator tunable filters is presented. The system and method are amenable to integration and are developed for on-board and on-chip automatic tuning of tunable filters without the use of a vector network analyzer and with minimal additional hardware. An analytical coupling matrix-based model of the tuning algorithm is developed to analyze and predict the performance of the tuning algorithm. The tuning model is verified with the automated tuning algorithm operating on a realized tunable filter. Finally, a low-cost hardware prototype for scalar transmission measurement for standalone implementation of the algorithm is also presented.
