Hi Darol,

Welcome to Agile Solutions. 

Yes, you are correct. We have not used any RF preselectors. 

We will create a place holder for RF filter before the LNA so that
desired filter can be installed(if required) for the target application.

Please check this link for off the shelf available filters
