Rf Connector Recommendation - Quectel SC690A Series Hardware Design

GSM/EVDO/CDMA/UMTS/TD-SCDMA/LTE
Wi-Fi/Bluetooth
⚫
NOTE
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.

5.6. RF Connector Recommendation

If you use RF connector for antenna connection, it is recommended to use the U.FL-R-SMT connector
provided by HIROSE.
