Note:
The function of W_DISABLE1# can be customized, please refer to the software porting guide.
3.7.2 BODYSAR
The FM150 module supports Body SAR function by detecting the DPR pin. The voltage level of DPR is
high by default, and when the SAR sensor detects the closing to human body, the DPR signal will be pulled
down. As a result, the module then lowers down its emission power to its default threshold value, thus
reducing the RF radiation on the human body. The threshold of emission power can be set by the AT
Commands. The definition of DPR signal as shown in the following table:
DPR signal
Function
High/Floating
The module keeps the default emission power.
Low
Lower the maximum emission power to the threshold value of the module.
3.8 ANT Tunable Interface
The module supports ANT Tuner interfaces with two different control modes, i.e. MIPI interface and 3bit
GPO interface. Through cooperating with external antenna tuner switch via the port of ANT Tuner, it can
flexibly configure the bands of antenna to improve the antenna’s working efficiency and save space for the
antenna.
