19 GHz Single-Ended-to-Balanced Modified Ladder-Lattice Filters Realized Using Periodically Polarized AlScN BAW Resonators
This paper presents two 19 GHz single-ended-to-balanced modified ladder-lattice filters realized with periodically polarized AlScN BAW resonators that eliminate the need for external baluns while achieving low insertion loss, high out-of-band rejection, and competitive performance for wireless communication applications.
