The Antenna Connector

When choosing antennas, customer should pay attentions to the connector on antenna that should match with the
connector on the module.
The dimension of the connector on SIM7200 is 2.6*2.6*1.25mm, which is from Hirose, and the part number is
U.FL-R-SMT (10), Use KLC-1401 (www.lccable.com) to attach antennas to connection points on the module, as
shown in Figure 18, likewise, customer can choose other vendor if the component's size match with U.FL-R-SMT
(10).
Match coaxial connections between the module and the antenna to 50Ω. Minimize RF cable losses to the antenna;
the recommended maximum cable loss for antenna cabling is 0.5 dB. To ensure best thermal performance, if
possible use the mounting holes to attach (ground) the device to the main PCB ground or a metal chassis.
