19 GHz Single-Ended-to-Balanced Modified Ladder-Lattice Filters Realized Using Periodically Polarized AlScN BAW Resonators
Demonstration of 19 GHz modified ladder-lattice filters with P3F AlScN resonators showing 1.3 dB and 1.58 dB min insertion loss, 5-6% fractional bandwidth, and 30-33 dB out-of-band rejection in compact footprints.
