Design and Fabrication of Centre Frequency and Bandwidth Tunable Cavity Filters
(University of Waterloo, 2014-12-18)To facilitate efficient utilization of limited and expensive frequency spectrum in communication system, fully tunable filters are highly demanded. Realizing an absolute constant bandwidth, a reasonable return loss, and a ... -
High-Performance Reconfigurable Piezoelectric Resonators and Filters for RF Frontend Applications
(University of Waterloo, 2022-09-08)A conventional RF frontend module consists of many filters where each filter is allocated for a specific frequency band. These filters are connected through multiplexing switch networks to support multi-band wireless ... -
Varactor-Based Tunable Planar Filters and Post-Fabrication Tuning of Microwave Filters
(University of Waterloo, 2012-10-25)Post-fabrication tuning of filters is usually realized by adding number of elements for tuning the frequency and/or controlling the couplings between the resonators. The task of these tuning elements is to control resonators ...
