Build LPFs with dot-terminations: high-frequency lowpass filters with flat passband responses ideal for digital signal transmissions can be fabricated withmicrostrip dot-terminations.(DesignFeature)(lowpass filters)
Lowpass filters with maximally flat group delay are ideal for digital signal transmission systems, since they allow pulsed signals to rise and fall smoothly and settle rapidly to final values without distortion. Filters such as the Bessel-Thomson lowpass filter have been used in these applications, although the configuration is reflective at stopband frequencies and can cause signal distortion with impedance mismatches. A better solution is the quasi-Gaussian absorptive lowpass filter, with flat group delay in the passband, good match at all frequencies, and absorptive rather than reflective behavior for stopband signals. An effective method for creating quasi-Gaussian ...
