We're looking at adding an antenna/component to our SoM RF connection that acts as a 50 ohm termination block. The goal is to block WIFI/BT connectivity for any circumstance, and leaving the connector open could have a coupling factor that is unacceptable to the client. Most 50 ohm termination blocks are SMA or larger. Our form factor requires a U.FL/MHF-1 connection. Would it be possible to create a termination block that connects directly onto the receptacle, or would a short cable to a FPCB w/ a load resistor be sufficient?
