The present invention is mainly applied in the field of radio frequency communication, especially a reverse protection device and method, which includes a radio frequency signal generation circuit to generate a radio frequency signal, and transmits the radio frequency signal to an output terminal through a transmission line, and the output terminal sends the radio frequency signal to the radio frequency Outside the signal source, the power divider extracts part of the signal power of the reverse input signal on the transmission line, and transmits part of the signal power to the detection unit and the amplification unit, and finally enters the comparison unit to compare the amplified DC voltage signal with the predetermined threshold For voltage comparison, if the amplified DC voltage signal exceeds the threshold voltage, a signal to disconnect the transmission line is output to the switch unit connected in series on the transmission line; otherwise, a signal to turn on the transmission line is output to the switch unit. Through the above embodiments, the influence of the existing overcurrent protection device on the output of radio frequency signals can be reduced, and it is suitable for high frequency radio frequency output devices with fast response speed.
Description
technical field [0001] The invention is mainly applied to the field of radio frequency measurement, in particular to a radio frequency signal source with a reverse protection function and a reverse protection method. Background technique [0002] The transmitting device is to give the required signal, but the device itself does not perform signal analysis, such as radio frequency signal source, etc.; the receiving device refers to that it has no signal output itself, and makes various analyzes by receiving signals from the outside world, such as spectrum analysis Instruments, oscilloscopes, etc. are receiving equipment. [0003] For the transmitting device, there may be a reverse input signal at its output, for example, the output terminal of the transmitting device is connected incorrectly, and at this time, if the power of the reverse input signal is too high, the circuit components of the transmitting device will be damaged. [0004] Such as figure 1 Shown is the struct...
