An inline RF bandpass filter (unbalanced). Solder through-hole SMA connectors (example: DigiKey P/N A97594-ND) to the ends and then populate your own LC ladder network on the 0603 pads.
Traces have 50 ohm characteristic impedance based on OSHPark 2-layer stackup, planes have been via stitched for better RF performance.
You may want to mount the board inside a small metal box for shielding.
