External Active Antenna Voltage
An external bias-T is required to provide voltage to an external antenna. A maximum of 16 V
DC may be applied to the External Ant. RF_In pin. See
Section 10.11 Powering an External
LNA (External Active Antenna).
Burnout Protection
The receiver can accept an external RF signal of up to -20 dBm with a DC voltage of
± 15 V
without risk of damage.
Jamming Rejection
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.
