Now I need to design a UHF band(300-3000M) microstrip filter.
The parameter is follow: passband about 30M with distortion less than 3dB and 50M out of passband the restrain should be more than 30dB
The size must be very small, and the CL is aslo the less, the better.
(For example: cf:2000M; 1970-2030M restrain<3db; <1920M or >2080M restrain>30db)
There is no article to show method can meet it.
Can you give some advice or aritcle to solve the problem
Thank you!
