PXS8 Hardware Interface Description 5 Antenna Interfaces 33 5 Antenna Interfaces 5.1 GSM/UMTS/CDMA Antenna Interface The PXS8 GSM/UMTS/CDMA antenna interface comprises a main GSM/UMTS/CDMA antenna as well as an optional UMTS/CDMA Rx diversity antenna to improve signal reliability and quality1. The interface has an impedance of 50. PXS8 is capable of sustaining a total mismatch at the antenna interface without any damage, even when transmitting at maximum RF power.
PXS8 Hardware Interface Description 5.1 GSM/UMTS/CDMA Antenna Interface 33 5.1.1 Antenna Installation The antenna is connected by soldering the antenna pads and their neighboring ground pads directly to the application’s PCB. The distance between the antenna pads and their neighboring GND pads has been optimized for best possible impedance. To prevent mismatch, special attention should be paid to these pads on the application’ PCB.
PXS8 Hardware Interface Description 5.2 GNSS Antenna Interface 33 5.2 GNSS Antenna Interface In addition to the RF antenna interface PXS8 also has a GNSS antenna interface. The GNSS antenna installation and connector are the same as for the RF antenna interface (see Section 5.1.1). For use with GPS and GLONASS it is recommended to use a GPS and GLONASS capable antenna. It is possible to connect active or passive GNSSS antennas. In either case they must have 50 Ohm impedance.
