4.3.2 Out-of-band blocking immunity
Out-of-band RF interference may degrade the quality and availability of the navigation solution.
Out-of-band immunity limit describes the maximum power allowed at the receiver RF input with no
degradation in performance. Minor violation of the immunity limit may reduce C/N0 of the received
signals but does not necessarily affect the overall receiver performance. However, a significant
violation may reduce receiver sensitivity or cause a complete loss of signal reception. The severity of
the interference depends on the repetition rate, frequency, signal level, modulation, and bandwidth
of the signal.
Figure 26 shows a typical out-of-band immunity level for the MAX-M10M RF input. The internal LNA
is in normal-gain mode (default). The measurement is done at room temperature using a test signal
with 64QAM modulation and 10 MHz bandwidth similar to an LTE signal.
If the out-of-band immunity limit is exceeded, it is recommended to verify that the receiver
performance is not affected or is at an acceptable level in the presence of interference.
Figure 26: MAX-M10M out-of-band immunity level at 400 - 1460 MHz and 1710 - 3300 MHz for the normal-gain mode
(default). Preliminary data subject to change.
Table 31 shows tabulated values for out-of-band immunity at selected cellular and Wi-Fi
frequencies.
