High-order quasi-reflectionless bandpass filters with improved passband flatness and good impedance matching both in-band and out-of-band are proposed in this work. The proposed design consists of conventional coupled-lines bandpass sections loaded with absorptive stubs at the input and output. Analysis shows that the absorptive stub is equivalent to a 2-pole bandstop filter. https://safeersappliancers.shop/product-category/siemens-hb656gbs6b-iq700-touch-control-multifunction-electric-built-oven/
