为了快速准确地设计并制作恒带宽窄带集总跳频滤波器，提出了一种随频率变化而 变化的负载结构。
For fast and accurate design and production of lumped constant bandwidth frequency-hopping(FH) narrowband filter, a load structure changing with frequency is introduced.
一般情况下，为使滤波器在任意频段都有良好的频率分辨力，可采用恒带宽带通滤波器，如收音机的选频。
Under normal circumstances, in order to filter at any frequency band have good frequency resolution, can be used with a broadband constant-pass filter, such as radio frequency-selective.
