For the MAX7037, what part numbers should be used instead of FI1 SAW filter (B39321B3741H110) if we need to work at 433MHz or 868MHz?

The SAW filters for 434MHz and 868MHz should be the TDK/Epcos B3743 and B3744, respectively.
This results in Tx output power at ~8dBm for 434MHz and ~3dBm for 868MHz at the SMA connector (sample size of one). There is no measured sensitivity data.
