For the module’s output power, the following is should be noted:
At GSM900 and GSM850 band, the module is a class 4 device, so the module’s output power should not exceed
33dBm, and at the maximum power level, the output power tolerance should not exceed +/-2dB under normal
condition and +/-2.5dB under extreme condition.
At DCS1800 and PCS1900 band, the module is a class 1 device, so the module’s output power should not exceed
30dBm, and at the maximum power level, the output power tolerance should not exceed +/-2dB under normal
condition and +/-2.5dB under extreme condition.

5. Antenna interface
There are three antenna ports for SIM800H, GSM antenna port named RF_ANT, Bluetooth antenna port named
BT_ANT and FM antenna port named FM_ANT_P, The RF interface of the three antenna ports has an
impedance of 50.The maximum gain of the GSM antenna gain should not exceed 3dBi considering the SAR
radio. And the maximum gain of the Bluetooth antenna gain shout not exceed 2dBi.1RDQWHQQDJDLQPD\EHXVHG
WKDWZRXOGH[FHHGWKH:(,53SRZHUOLPLWLQ0+]EDQG
z The input impendence of the antenna should be 50, and the VSWR should be less than 2.
z It is recommended that the GSM antenna and the BT antenna be placed as far as better.
z The isolations of the three antenna should be bigger than 30d%
5.1 GSM Antenna Interface
There is a GSM antenna pad named RF_ANT for SIM800H 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.

There are some suggestions to components placing and lying for GSM and Bluetooth RF traces:
z The RF connector is used for conducted test, so keep it as close as pin RF_ANT;
z Antenna matching circuit should be closed to the antenna;
z Keep the RF traces as 50˗
z The RF traces should be kept far away from the high frequency signals and strong disturbing source.
