Filtering functions with reduced fabrication sensitivity

A new category of filtering functions is proposed. Reflection zeros are redistributed to provide higher attenuation lobes near the band edge compared to the lobes near the center frequency. The ripple in the passband is smallest near the band edges mitigating the sensitivity of return and insertion...

Description
Summary:A new category of filtering functions is proposed. Reflection zeros are redistributed to provide higher attenuation lobes near the band edge compared to the lobes near the center frequency. The ripple in the passband is smallest near the band edges mitigating the sensitivity of return and insertion loss within the passband while providing better selectivity compared to chained function filters.
