(EGSM900,WCDMA B5/B8,
LTE B5/B8/B12/B13/B20/B26/B28)
Cable Insertion Loss: < 1.5dB
(DCS1800, WCDMA B1/B2/B4, LTE B1/B2/B3/B4/B25)
Cable insertion loss: < 2dB
(LTE B7)
1)
It is recommended to use a passive GNSS antenna when LTE B13 is supported, as the use of active
antenna may generate harmonics which will affect the GNSS performance.
5.3.2. Recommended RF Connector for Antenna Installation
If RF connector is used for antenna connection, it is recommended to use U.FL-R-SMT connector provided
by Hirose.
Figure 36: Dimensions of the U.FL-R-SMT Connector (Unit: mm)
U.FL-LP serial connectors listed in the following figure can be used to match the U.FL-R-SMT.
