●If the module stays at maximum voltage for a long time, it may be
damaged;
● The power supply pin has certain surge-resistance ability, but the
potential pulse is higher than the maximum power supply voltage;
●The power supply is not advisable to be below 3.0V, or the RF
parameters will be influenced at different degree.
● For max 30dBm, voltage is no less than 4.75V，or RF parameters
will be affected to different extend.

● If the module stays at maximum communication level for a long
time, it may be damaged;
● There are various ways to switch communication level, but it will
affect the whole power consumption to a large extend.

dBm
● Due to the error of the materials, each LRC component has ±0.1%
error, so error accumulation will occur since multiple LRC
components are used in the whole RF circuit, and the transmitting
currents will be different at different modules;
● The power consumption can be lowered by lowering the
transmitting power, but the efficiency of the internal PA will be
decreased by lowering transmitting power due to various reasons;
● The transmitting power will be lowered by lowering the power
supply voltage.

● The sensitivity is tested under the air data rate 1.3kbps;
● Due to the error of the materials, each LRC component has ±0.1%
error, so error accumulation will occur since multiple LRC
components are used in the whole RF circuit, and the transmitting
currents will be different at different modules;
●The receiving sensitivity will be reduced and communication range
will be shortened while increasing the air data rate.
