[0048] Four embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0049] Embodiment 1

[0050] In Embodiment 1, a comb spectrum generator is used to generate a signal, and the parameters of all frequency multipliers and power dividers are represented by letters. The composition and connection manner between components in Embodiment 1 are as described below:

[0051] A comb spectrum generator, the input end of the comb spectrum generator is used to receive a frequency signal;

[0052] A surface acoustic wave filter A, the input end of the surface acoustic wave filter A is connected to the output end of the comb spectrum generator;

[0053] An amplifier A, the input end of the amplifier A is connected to the output end of the surface acoustic wave filter A;

[0054] A surface acoustic wave filter B, the input end of the surface acoustic wave filter B is connected to the output end of the amplifier A;

[0055] A low-pass filter, the input end of the low-pass filter is connected to the output end of the surface acoustic wave filter B;

[0056] An amplifier B, the input end of the amplifier B is connected to the output end of the low-pass filter;

[0057] A surface acoustic wave filter C, the input end of the surface acoustic wave filter C is connected to the output end of the amplifier B.

[0058] A 2-way power divider, the input end of the 2-way power divider is connected to the output end of the surface acoustic wave filter C;

[0059] A non-frequency-multiplied output module, the input end of the non-frequency-multiplied output module is connected to one output end of the 2-way power divider, and outputs a non-frequency-multiplied signal externally;

[0060] A frequency-multiplied output module, the input end of the frequency-multiplied output module is connected to the other output end of the 2-way power divider, and outputs a frequency-multiplied signal externally.

[0061] The non-frequency-multiplied output module assembly includes:

[0062] An attenuator, the input end of the attenuator is connected to one output end of the 2-way power divider, and outputs a signal externally.

[0063] The frequency-multiplied output module assembly includes:

[0064] An N - frequency multiplier, the input end of the N - frequency multiplier is connected to an output end of a 2 - way power divider, and outputs an N - times frequency signal externally;

[0065] A band - pass filter, the input end of the band - pass filter is connected to the output end of the N - frequency multiplier;

[0066] A P - way power divider, the input end of the P - way power divider is connected to the output end of the band - pass filter.

[0067] The principle of Embodiment 1 is described as follows:

[0068] As shown in the attached Figure 1 figure, a 100 MHz signal enters the comb - spectrum generator. The comb - spectrum generator outputs a series of spectra with an interval of 100 MHz. The signals below 3 GHz are taken out for output, and the typical value of the output power at 3 GHz is about - 20 dBm. The model of the comb - spectrum generator of this utility model is the YZCSG - 19 series, and the frequency range of the output signal is 200 MHz to 5 GHz. However, the output frequency is a multiple of 100 MHz. Therefore, for the general frequency - multiplying component in this embodiment, it only requires that the comb - spectrum generator outputs a frequency of 100 * Q MHz, where Q is a positive integer, Q is greater than or equal to 2 and less than or equal to 50. After the comb - spectrum generator outputs the signal, the required signal is taken out by the surface acoustic wave filter A, and then amplified by the amplifier 1. Since the out - of - band spurious suppression of the surface acoustic wave filter is only about 30 dBc, and the output signal of the comb - spectrum generator is small, it needs to be amplified and filtered multiple times to meet the system usage requirements. Therefore, after the amplifier A, a surface acoustic wave filter B, a low - pass filter, an amplifier B, and a surface acoustic wave filter C are connected. This general frequency - multiplying component only requires that the comb - spectrum generator outputs a frequency below 3 GHz. Therefore, the output frequency from the surface acoustic wave filter C is 100 * Q MHz, where Q is a positive integer, Q is greater than or equal to 2 and less than or equal to 30. The signal output from the surface acoustic wave filter C enters the 2 - way power divider. The 2 - way power divider divides the signal into 2 paths. One path of the 100 * Q MHz signal is output after passing through the attenuator, and the other path of the 100 * Q MHz signal passes through the N - frequency multiplier and the band - pass filter to filter out spurious signals and obtain a 100 * Q * N MHz signal (the value range of N is 2, 3, 4, 8, 16), which is divided into P paths of 100 * Q * N MHz signals for output by the P - way power divider (the value range of P is 2, 3, 4).

[0069] Embodiment 2

[0070] In Embodiment 2, a comb - spectrum generator is used to generate signals, and the parameters of all frequency - multipliers and power dividers are represented by specific numbers. The composition and the connection method between devices in Embodiment 2 are described as follows:

[0071] A comb - spectrum generator, the input end of the comb - spectrum generator is used to receive frequency signals;

[0072] Surface acoustic wave filter A, the input end of the surface acoustic wave filter A is connected to the output end of the comb spectrum generator;

[0073] Amplifier A, the input end of the amplifier A is connected to the output end of the surface acoustic wave filter A;

[0074] Surface acoustic wave filter B, the input end of the surface acoustic wave filter B is connected to the output end of the amplifier A;

[0075] Low-pass filter, the input end of the low-pass filter is connected to the output end of the surface acoustic wave filter B;

[0076] Amplifier B, the input end of the amplifier B is connected to the output end of the low-pass filter;

[0077] Surface acoustic wave filter C, the input end of the surface acoustic wave filter C is connected to the output end of the amplifier B.

[0078] 2-way power divider, the input end of the 2-way power divider is connected to the output end of the surface acoustic wave filter C;

[0079] Non-frequency-doubled output module, the input end of the non-frequency-doubled output module is connected to one output end of the 2-way power divider, and outputs a non-frequency-doubled signal externally;

[0080] Frequency-doubled output module, the input end of the frequency-doubled output module is connected to the other output end of the 2-way power divider, and outputs a frequency-doubled signal externally.

[0081] The non-frequency-doubled output module assembly includes:

[0082] Attenuator, the input end of the attenuator is connected to one output end of the 2-way power divider, and outputs a signal externally.

[0083] The frequency-doubled output module assembly includes:

[0084] 3x frequency multiplier, the input end of the 3x frequency multiplier is connected to one output end of the 2-way power divider, and outputs a 3x frequency-doubled signal externally;

[0085] Band-pass filter, the input end of the band-pass filter is connected to the output end of the 3x frequency multiplier;

[0086] 3-way power divider, the input end of the 3-way power divider is connected to the output end of the band-pass filter.

[0087] The principle of Embodiment 2 is described as follows:

[0088] In this embodiment, this general frequency-doubled component realizes the output of 1 path of 2 GHz signal and 3 paths of 6 GHz signals. As shown in the appendix Figure 2As shown, a 100M clock signal enters the comb spectrum generator, generating a series of output signals of the comb spectrum generator. Then, the desired signal is extracted by the surface acoustic wave filter A and amplified by the amplifier A. Since the out-of-band spurious suppression of the surface acoustic wave filter is only about 30 dBc and the output signal of the comb spectrum generator is small, multiple amplifications and filtrations are required to meet the system usage requirements. In this case, a 2GHz signal is extracted. Therefore, after the amplifier A, a surface acoustic wave filter B and a low-pass filter are connected (since the 2GHz surface acoustic wave filter has no suppression in the frequency band above 3.5G, a low-pass filter is used to filter out the spurious signals above 3.5G), followed by an amplifier B and a surface acoustic wave filter C. The signal output from the surface acoustic wave filter C enters a 2-way power divider. The 2-way power divider divides the signal into two paths. One path of the 2GHz signal is directly output after attenuation, and the other path of the 2GHz signal is multiplied by 3 and the spurious signals are filtered out by a band-pass filter to obtain a 6GHz signal, which is divided into three paths of 6GHz signals by a 3-way power divider and output.

The X2 - frequency multiplier (the value range of X2 is 2, 3, 4, 8, 16) generates a signal of 100 * X1 * X2 MHz, and after being filtered and amplified by the surface acoustic wave filter B, the low - pass filter, the amplifier B, and the surface acoustic wave filter C, it enters the 2 - way power divider.
