High resolution integrated passive phase shifters for future wireless communications

Amirkhanzadeh, Robabeh (2015) High resolution integrated passive phase shifters for future wireless communications. PhD thesis, Victoria University.

Abstract

This thesis focuses on the implementation of high resolution phase shifter devices for adaptive cancelling applications. Cancelling is a potential replacement for filtering in wireless handsets, where the area allocated to filtering is becoming excessive due to the growing numbers of transmission frequencies. Cancelling circuits have the potential to be integrated directly in silicon as part of the radio circuit. Adaptive cancelling requires precise adjustments of the gain and phase of the reference RF signal.
