Embodiment Construction

[0024] The device and method of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] In FIG. 3 is a schematic diagram of the radio frequency RMS power detection method of the present invention.

[0026] The radio frequency RMS power detection method of the present invention comprises the following steps:

[0027] In the first step, the radio frequency signal to be detected is divided into two signals with the same frequency and equal power;

[0028] The second step is to perform multiplication processing on the two signals after the split, and output the result of the operation;

[0029] The third step is to perform low-pass filtering processing on the obtained calculation results, and output the processing results;

[0030] The fourth step is to calculate the obtained filtered signal and look up the table to obtain the RMS power of the radio frequency.

Description

technical field [0001] The invention relates to power detection of digitally modulated radio frequency signals in the communication field, in particular to a radio frequency RMS power detection device and method. Background technique [0002] In today's highly developed 3G mobile communication technology, digital modulation and demodulation technology has become a widely used technology, resulting in more complex radio frequency signals, and the power detection technology for such wireless signals is also more complex. [0003] The current radio frequency signal power detection technology used in wireless communication equipment is as follows: [0004] 1. Use a radio frequency diode detector to detect the power of the radio frequency signal. As shown in Figure 1, the radio frequency diode outputs the envelope of the radio frequency signal, but this method can only detect the peak power of the signal, and cannot detect the RMS power of the signal, that is, for Digitally modu...
