SAW filter frequency response verify

Hi, all

Recently I have a project that use two SAW filters in RF board, but I want to know impedance matching of these filters. How do I verify that ?


Thanks,

You can start by measuring the filters on a network analyzer and evaluating their S11 and S22 for impedance. Then you provide a conjugate match to these impedances respetively.

hi all,
typically, SAW filter manufacturers provide input and output matching networks specifically designed for their filters. I have tried Vectron Saw filters and there is no better way to match them.
hope this helpsw

Best way is with a sweeper and spectrum analyzer but too expensive.
I think that manufacturers datasheet must include all you need.
