Notes:
• As noted in section 7.5.4, the 869 MHz SAW filter does not cover the whole European 863 — 870 MHz
frequency band when used in a 50 ohms environment. Hence the output power degradation at the lowest
frequencies. For applications in the 863 — 870 MHz band it is recommended that an appropriate SAW filter be
implemented or that the SAW response tuned by external matching.
• The SAW filter ripple references are the insertion loss of each SAW at 869 MHz and 915 MHz.
