As noted inSection 4.3.1 “SAW Filter Plot”, the 869 MHz SAW filter does not cover the entire European 863-870 MHz frequency band
when used in a 50
MHz band, it is recommended that an appropriate SAW filter be implemented or that the SAW response is tuned by external matching.
The SAW filter ripple references are the insertion loss of each SAW at 869 MHz and 915 MHz.
