● 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 250kbps;
● 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.

● To work within the recommended frequency can assure the modules
to meet all the parameters;
● It is recommended to avoid the crowded integral frequency such as
433.0MHz, 868.0MHz, 915MHz, 240MHz etc.
