I am struggling with a UHF band pass filter. Here are the specs:
Passband frequency range: 416 - 458 MHz
Center frequency: 436.5 MHz
Stopband attenuation: 60 dB
Loss: 1 dB or better
Filter order: 3
I have done the simulation in Filter solutions and when I buid it it doesnt work. I please want if somebody can do the simulation in MWO office and see how it looks like. I am not experienced with MWO. Any suggestions are welcome.
Your comments and help will be highly appreciated.
Hello, this message is quite old, but I'll post an aswer nonetheless.
I passed your filter data to Elsie, the software we use for this kind of work.
Here are the resulting components. It's a Cauer filter, 3rd order, that meets your specifications, and the components' values seem reasonable.
