Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0020] like Figure 1 As shown, an ultra-wideband, multi-frequency combiner structure of an embodiment of the present invention includes an ultra-wideband high-frequency part, a connection structure for high-frequency and low-frequency signals, and a low-frequency multi-frequency structure. The ultra-wideband high-frequency part adopts a high-pass structure 2, the connection structure for high-frequency and low-frequency signals adopts a low-pass structure 3, and the low-frequency multi-frequency structure adopts a resonant common cavity one-to-many structure.

[0021] The high-pass structure 2 is used to achieve a passband of 1700-6000 MHz and suppress 50 dB of DC-1000 MHz.

[0022] In this embodiment, the ultra-wideband, multi-frequency combiner structure is configured as a three-part structure including a wideband high-frequency part, a connection structure for high-frequency and low-frequency signals, and a low-frequency multi-frequency structure, wherein the wideband high-frequency part adopts a high-pass structure 2, the connection structure for high-frequency and low-frequency signals adopts a low-pass structure 3, and the low-frequency multi-frequency structure adopts a resonant common cavity one-division-multiple structure, thereby effectively achieving the product index requirements of the ultra-wideband, multi-frequency combiner.

[0023] Secondly, the high-frequency part of the ultra-wideband adopts high-pass structure 2, which can be used to achieve a passband of 1700-6000MHz, thereby achieving an ultra-wideband passband.

[0024] In addition, the high-pass structure 2 suppresses 50dB from DC to 1000MHz, thereby achieving a suppression effect on the low-end structure.

[0025] Optionally, the ultra-wideband and multi-frequency combiner structure further includes an ANT port, and the high-pass structure 2 is connected to the ANT port.

[0026] In this embodiment, the high-pass structure 2 is connected to the ANT port, and wireless data transmission can be achieved through the ANT port.

[0027] Optionally, the low-pass structure 3 is connected to the high-pass structure 2 , and the low-pass structure 3 is used to achieve a passband of DC-1000 MHz, and to generate 40 dB suppression for 1700-3000 MHz and 50 dB suppression for 3000-6000 MHz.

[0028] In this embodiment, the ultra-wideband and low-frequency bands can be effectively combined by low-pass switching, thereby achieving the combination of ultra-wideband and multiple low-frequency bands. Secondly, the low-pass structure 3 can suppress the harmonic resonance generated by each low-frequency band at the high-frequency position while achieving the passband frequency.

[0029] Optionally, the resonant common cavity one-to-many structure is connected to the low-pass structure 3 .

[0030] In this embodiment, the frequency band of the resonant common cavity one-to-many structure includes but is not limited to 700-800 MHz / 900 MHz.

[0031] Alternatively, as Figure 1 As shown, the resonant common cavity one-to-many structure includes a low-frequency common cavity connecting rod 1 and a low-frequency common cavity resonator 4. The low-frequency common cavity connecting rod 1 is connected to the low-pass structure 3, and the low-frequency common cavity connecting rod 1 and the low-frequency common cavity resonator 4 are capacitively coupled.

[0032] In this embodiment, the low-frequency common cavity connecting rod 1 and the low-frequency common cavity resonator 4 are capacitively coupled to transmit the signal to the low-frequency common cavity resonator 4. The low-frequency common cavity resonator 4 then couples with the resonators in other frequency bands to transmit the signal to each low-frequency band. Therefore, through the capacitive coupling structure of the low-frequency common cavity connecting rod 1 and the low-frequency common cavity resonator 4, a strong time delay can be achieved and the product can be ensured to have a high intermodulation index.

[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
