Among them, a nameplate mounting position 7 is provided on the left side plate 5, and the nameplate mounting position 7 is used to mount the nameplate of this device;

[0042] A receiving module 9; the receiving module 9 is used to receive radio frequency signals and preprocess the radio frequency signals;

[0043] A power amplifier module 10; the power amplifier module 10 is provided with an output antenna and a power amplifier. The signal input end of the power amplifier module 10 is connected to the receiving module 9, and the signal output end of the power amplifier module 10 is connected to the output port or the output antenna. The power amplifier module 10 is used to amplify the preprocessed radio frequency signal into an ultra-short wave signal by the power amplifier and output it through the output antenna. The power amplifier module 10 is also used to output the radio frequency signal as a digital signal and output it from the output end of the power amplifier module 10;

[0044] The power amplifier module 10 can achieve higher power output on the premise of ensuring communication quality, thereby expanding the communication distance. The device up-converts the processed signal to the ultra-short wave frequency band for wireless transmission through the output antenna. The power amplifier module 10 allows signals to be transmitted within a specific frequency band to avoid interference with the signals of other communication devices, and at the same time, the number of up-converted carriers is not less than 2, which can ensure that the device can process and transmit multiple carrier signals simultaneously.

This expansion of the frequency band width makes the ultra-short wave signal transmitting device have obvious advantages in data transmission efficiency and capacity. Also, because the ultra-short wave has a shorter wavelength, the electromagnetic interference received during its signal transmission is relatively small, which ensures the stability and reliability of signal transmission.
