● The power supply voltage is not recommended to be
lower than the recommended value. When the power
supply voltage is lower than the recommended value, the
RF parameters will be affected to varying degrees.

● The communication level is higher than the maximum
value of the module communication level, there is a high
risk of burning the module;
● Although there are many ways to change the
communication level, it will greatly affect the power
consumption of the whole machine.

● Since the material itself has a certain error, a single
LRC component has an error of ±0.1%. However, since
a plurality of LRC components are used in the entire RF
loop, there is a case where error accumulation occurs,
resulting in a difference in transmission current of
different modules;
● Reducing the transmit power can reduce power
consumption to some extent, but reducing the transmit
power emissions for a number of reasons reduces the
efficiency of the internal PA;
● Transmit power will decrease as the supply voltage
decreases
