| 总结: | This work presents a novel synthesis procedure for designing Ultra-wideband (UWB)
bandpass filters. Based on the desired filter specifications, filter topology is selected.
Distributed equivalent circuit of selected topology is extracted. Due to narrowband
approximations, narrowband synthesis filter theory cannot be applied on UWB filter
designs. Hence, there is a scope for development of exact synthesis theory
for UWB bandpass filters. Filtering function is calculated from the distributed
equivalent circuit model. In this work, the synthesis procedure is implemented on
quasi-Chebyshev type filtering function. Synthesis is done on the calculated filtering
function by setting specific goals derived from the given specifications. In this way,
the filtering function unknowns are achieved which are later used to calculate the
optimum solution for filter characteristic impedances. |
