Nw I want to design a filter:
frequency range: 1000MHz~1120MHz
rejection@+/-40MHz=40dB,that's to say,in the 960MHz and 1160MHz the rejection sould be great than 40dB,
the size of filter is restricted as:lenth x width less than 100mm x40mm,any one can give some advice?
PM if you have good ideas.
Thx
regards

You sholud read the selected chapters from the "Microstrip Filters for RF/Microwave Appl" by
Hong, Lancaster. This book was downloaded to the "e-books up/down" forum some time ago.
Probably you will find the answer.
I am quite new in ecllipse filter, what is your application? Why you need such this type of filters, is it can implemented in lump elements or a DSP windows in baseband?
