Circuit arrangement for reducing passband ripple of a bandpass filter |
摘要 |
A bandpass filter arrangement that includes a weakly coupled coaxial resonator to reduce the fluctuation in frequency response of the filter arrangement. A bandpass filter is coupled to the output of a low noise amplifier. The characteristic fluctuation in frequency response in the passband of the bandpass filter is reduced with a coaxial resonator that is disposed proximate the filter arrangement.
