Abstract in another language

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 Q m and inductor losses Q L . This work outlines the concept and design aspects. Also various examples will be proposed to show the main benefits of this approach.
