Looking for Ceramic Filter 515MHz~695MHz

I'm looking for 6MHz RF channel filters for 515~695MHz band to improve transimiter far-out noise. It could be a tubular filter or on a daughter board.

Any one know vendor good at this?

What 's price ballpark?

Thanks for your help.

Hi,
if it isnt a power level system, than is a typical case for SAW filter...
Do you means with "tubular filter" a cavity or some helical filter pls?

This is used for PA mask regulation so insertion loss can be high. It has to be a ceramic filter.
