9.5.3. Burnout Protection
The receiver accepts without risk of damage a signal of +10 dBm from 0 to 2 GHz carrier
frequency, except in band 1560 to 1610 MHz where the maximum level is –10 dBm.
9.5.4. Jamming Rejection – Active Interference Cancellation
Jamming Rejection can be used for solving narrow band (CW) EMI problems in the
customer’s system. It is effective against narrow band clock harmonics. Jamming
Rejection is not effective against wide band noise, e.g. from a host CPU memory bus or
switching power supply because these sources typically cannot be distinguished from
thermal noise. A wide-band jamming signal effectively increases the noise floor and
reduces GNSS signal levels.
Please refer to Section 4.9 Jamming Rejection – Active Interference Cancellation (AIC).
