Lowpass filters may achieve the effects of bandpass filtering by heterodyning the bandpass wave to obtain the "in-phase '~ and "quadrature" components and filtering these with suitable lowpass filters. The impulse responses for the lowpass filters are determined in a simple way from the desired band

## Abstract A highly selective superconducting ultraβwideband filter with a passband from 125 to 260 MHz is designed and demonstrated using a microstrip structure. The filter is designed according to a circuit model for an optimum shortβcircuited stub transmissionβline filter and consists of 10 shu
