Notes:
• 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.
