The integration of multiple bands and higher power standards lead to enhanced interference problems and make higher attenuation levels in next-gen RF-Front-Ends necessary. This paper introduces an all-pass based BAW filter design concept for notch, band-stop and band-pass filter topologies to indicate the possibilities and the impact of key parameters like material electromechanical coupling factor k-{eff}^2, piezoelectric material quality factor Qm and inductor losses QL. This work outlines the concept and design aspects. Also various examples will be proposed to show the main benefits of this approach.
