Hardware Notice:
When designing the power supply circuit for the module, it is recommended to reserve more than 30% of
the remaining amount, and the whole machine is beneficial for long-term stable operation;
；
The current required for the moment of launch is large but often because the launch time is extremely
short, the total energy consumed may be smaller;
When the customer uses an external antenna, the impedance matching degree between the antenna and
the module at different frequency points will affect the magnitude of the emission current to varying
degrees;
The current consumed by the RF chip in the pure receiving state is called the receiving current. Some RF
chips with communication protocols or developers have loaded some self-developed protocols on the
whole machine, which may cause the receiving current of the test to be too large
；
When the customer uses an external antenna, the impedance matching degree between the antenna and
the module at different frequency points will affect the magnitude of the emission current to varying
degrees
；
The shutdown current is often much smaller than the current consumed by the power supply part of the
whole machine at no load, without excessive demand;
Due to the inherent error of the material itself, a single LRC component has an error of ±0.1%, but
hesitant to use multiple LRC components in the entire RF loop, there will be accumulation of errors,
resulting in differences in the emission current and the receiving current of different modules
；
Reducing the transmit power can reduce power consumption to a certain extent, but reducing the transmit
power transmission for many reasons will reduce the efficiency of the internal PA.
