5.3.5. Recommended Manufacturers of RF Connector and Cable
RF connecters and cables by I-PEX are recommended. For more details, visit https://www.i-pex.com.
5.4. Antenna Requirements
The following table shows the requirements on WCDMA, LTE, 5G NR antenna and GNSS antennas.
Table 35: Antenna Requirements
It is recommended to use a passive GNSS antenna when LTE B13 or B14 is supported, as the use of
active antenna may generate harmonics which will affect the GNSS performance.
