SENSITIVITY FLATNESS
863
Measured in FSK mode only. OOK sensitivity characteristics will be similar. The sensitivity difference along the band remains inside
the ripple performance of the SAW filter (the nominal passband of the 869 MHz SAW filter is 868-870 MHz). The SAW filter ripple
response is referenced to its insertion loss at 869 MHz and 915 MHz for each filter.
