TYPICAL PERFORMANCE CHARACTERISTICS
Channel Selectivity and Blocking:
Note:
Phase Noise Performance in the 433, 868 and 915 MHz Bands:
(Measured under typical conditions: T
 LNA gain maximum, filter bandwidth 67 kHz, data rate 9.6 kbps, AFC switched off, FSK deviation ± 45 kHz, V
 Measured according to the descriptions in the ETSI Standard EN 300 220-1 v2.1.1 (2006-01 Final Draft), section 9
 The ETSI limit given in the figure is drawn by taking -106dBm at 9.6kbps typical sensitivity into account, and corresponds to
receiver class 2 requirements (section 4.1.1)
