Absorptive near-Gaussian low pass filter design with applications in the time and frequency domain

The work presented here is for the design of an absorptive low pass filter for use in the time and frequency domain. The filter presented is absorptive in the stop band, flat in group delay to twice the half power frequency and near-Gaussian in shape. The design of the low pass filter is general with design examples in microstrip and coplanar waveguide at 40 GHz. Frequency domain measurements to 110 GHz and time domain measurements at 40 Gbits/s are presented. The absorptive filter presented has uses in pulse shaping, rise time alteration and harmonic matching.
