Abstract:
Multiplexing circuits with bulk acoustic wave (BAW) resonators as network elements for higher performance are provided. Multiplexing networks which support newer fourth generation (4G) and fifth generation (5G) standards may include a combination of multiplexers having a number of radio frequency (RF) filters connected to an antenna at the same time. One critical aspect of such a multiplexer design is the loading of these filters to each other, in which the static capacitance presented by a filter can be beneficial or detrimental to other filters in the multiplexing network. Aspects of the present disclosure introduce a BAW resonator to improve multiplexing network performance using the frequency-dependent capacitance, resonance, and/or anti-resonance of the BAW resonator.
