5. Antenna interface
There are three antenna ports for SIM800, GSM antenna port named RF_ANT, Bluetooth antenna port named
BT_ANT, The RF interface of the three antenna ports has an impedance of 50Ω.The maximum gain of the
antenna gain should not exceed 3dbi considering the SAR radio.
The input impendence of the antenna should be 50Ω, and the VSWR should be less than 2.
It is recommended that the GSM antenna and the BT antenna be placed as far as better.
The isolations of the three antenna should be bigger than 30db
5.1 GSM Antenna Interface
There is a GSM antenna pad named RF_ANT for SIM800 the connection of the antenna must be decoupled
from DC voltage. This is necessary because the antenna connector is DC coupled to ground via an inductor for
ESD protection.
The external antenna must be matched properly to achieve best performance, so the matching circuit is
necessary, the connection is recommended as following:

5.2 Bluetooth antenna interface
The module provides a Bluetooth antenna interface named BT_ANT.

recommended as 1.2NH and C202 is 1.5pF, C201 are not SMD.
There are some suggestions to components placing and lying for GSM and Bluetooth RF traces:
The RF connector is used for conducted test, so keep it as close as pin RF_ANT;
Antenna matching circuit should be closed to the antenna;
Keep the RF traces as 50Ω；
The RF traces should be kept far away from the high frequency signals and strong disturbing source.

Federal Communication Commission Interference Statement
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1)This device may not cause harmful interference, and (2) this device must
accept any interference received,including interference that may cause undesired operation.
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant toPart 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the interference by one of the following
measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for
Compliancecould void the user's authority to operate this equipment.
This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
RF Exposure Compliance
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment.The antenna(s) used for this transmitter must be installed to provide a separation distance of at
least20 cm from all persons and must not be co-located or operating in conjunction with any other antenna
orTransmitter.
This device is intended only for OEM integrators under the following conditions:
1) The antenna must be installed such that 20 cm is maintained between the antenna and users, and
2) The transmitter module may not be co-located with any other transmitter or antenna.
As long as 2 conditions above are met, further transmitter test will not be required. However, the OEM
integrator is stillresponsible for testing their end-product for any additional compliance requirements
required with this module installed
IMPORTANT NOTE: In the event that these conditions can not be met (for example certain laptop
configurations or co-location with another transmitter), then the FCC authorization is no longer
considered valid and the FCC ID can not be usedon the final product. In these circumstances, the OEM
integrator will be responsible for re-evaluating the end product(including the transmitter) and obtaining
a separate FCC authorization.

End Product Labeling:
This transmitter module is authorized only for use in device where the antenna may be installed such
that 20 cm may bemaintained between the antenna and users. The final end product must be labeled in a
visible area with the following: “Contains
FCC ID:UDV-201314. The grantee's FCC ID can be used only when all FCC compliance requirements
are met.
Manual Information To the End User
The OEM integrator has to be aware not to provide information to the end user regarding how to install or
remove this RF module in the user’s manual of the end product which integrates this module.
The end user manual shall include all required regulatory information/warning as show in this manual.
