Dear ali ,

   See suggestions below, please!

1. Design your matching circuit and EMC circuit according to the 50 ohm antenna solution.

2. Reserve RXN for RX balun

In this way, the signal can be received either single-ended or differential.

Solutions for 50OHM single-ended solution will sent to your email. Pay attention to checking it, please!

Have a nice day!

VSS(TX) pin should be connected to GND, so you are right.

  VSS(TX) on PN7150 is TVSS.
