5.2 RF Antenna Connector
SIM7600E-PCIE have 3 antenna connectors, one of which is the GSM/UMTS/LTE main antenna connector, the
others are UMTS/LTE auxiliary antenna connector and GPS/GLONASS/BD antenna connector. Recommended
antenna characteristics of SIM7600E-PCIE are described by 2 following tables.
Table 20: Recommended Passive Antenna Characteristics
Gain > -3dBi (Avg)
Input impedance 50 ohm

The RF connector in the module side is an ultra small surface mount coaxial connector (Part Number:
U.FL-R-SMT, vended by HRS). It has high performance with wide frequency range, surface mountable and
reflows solderable. Following are parameters (Figure 19). Certainly user can visit
http://www.hirose-connectors.com/ for more information.
To get good RF performance in user’s design, SIMCom suggests user to use the matching RF adapter cable
which is also supplied by HRS (Part Number: U.FL-LP（V）-040), the following figure (Figure 20) is the
dimensions of U.FL series RF adapter cable. User can contact SIMCom for more information.
