In addition, the temperature of high-power power amplifier chips will increase during operation, making it difficult to dissipate heat and shortening its operating life. In addition, high-power power amplifier chips are usually export-controlled product items and are not easy to obtain. Summary of the invention

The solid conductive body 211 has a first surface 211a and a plurality of side surfaces 211b connected to the first surface 211a. The first separators 212 ( Figure 210 first separators 212 are schematically shown in FIG. 1 and are disposed on the first surface 211a of the solid conductive body 211. The first separators 212 separate a plurality of first resonance channels C1 ( Figure 2 10 first resonance channels C1 are schematically shown in FIG. 1 ).

In this embodiment, the signal transmitting end 215 may be located at or close to a center of the second surface 211c of the solid conductive body 211.

[0024] It is worth noting that, in the present embodiment, the arrangement of these first resonance channels C1 can be symmetrical to the arrangement of these second resonance channels C2. In detail, the number of these first resonance channels C1 in the present embodiment is the same as the number of these second resonance channels C2. These first resonance channels C1 are arranged in annular shapes at equal angles (for example, 36 degrees in the present embodiment) around the first common region R1, and these second resonance channels C2 are arranged in annular shapes at equal angles around the second common region R2. In addition, a position of each first resonance channel C1 corresponds to a position of one of these second resonance channels C2 in a one-to-one symmetrical manner, and an appearance of each first resonance channel C1 corresponds to an appearance of one of these second resonance channels C2 in a one-to-one symmetrical manner. However, in another embodiment, the arrangement of these first resonance channels can be asymmetrical to the arrangement of these second resonance channels according to design requirements.

[0025] In the present embodiment, a shape and a position of the signal receiving end 213 may be symmetrical to a shape and a position of the signal transmitting end 215, respectively. The signal receiving end 213 and the signal transmitting end 215 may be a cone, respectively. The bottom diameter D1 of the cone is, for example, 5 to 7 mm, the top diameter D2 is, for example, 0.2 to 2 mm, and the height H1 is, for example, 2 to 5 mm. The ratio of the bottom diameter D1, the top diameter D2, and the height H1 of the cone is, for example, approximately 6:1:3.5. The solid conductive body 211, the first separators 212, the second separators 214, the signal receiving end 213, and a signal transmitting end 215 of the present embodiment may be integrally formed, and the material is metal (including a single metal or alloy). However, in another embodiment, the shape and position of the signal receiving end may be asymmetrical to the shape and position of the signal transmitting end according to design requirements.

[0026] Please refer to Figure 1 , Figure 2 and Figure 4 , each circuit board 220 disposed on the corresponding side surface 211b of the solid conductive body 211 has a second end 224 opposite to the first end 222. The second end 224 of each circuit board 220 closes one of the second resonance channels C2. The lower cover 240 is disposed on the second partitions 214, and the lower cover 240 can be fixed to the second partitions 214 by a plurality of screws (not shown). The second resonance channels C2 are located in a second accommodation space formed by the lower cover 240, the second ends 224 of the circuit boards 220 and the second surface 211c of the solid conductive body 211.

[0027] In this embodiment, a ground layer (not shown) on the back side (facing the corresponding side 211b of the solid conductive body 211) of each circuit board 220 can electrically contact the solid conductive body 211. In addition, a power amplifier element 228 (for example, a power amplifier chip) is disposed on a conductive trace 226 on the front side (opposite to the corresponding back side) of each circuit board 220.

[0028] In the present embodiment, the circuit boards 220 are fixed to the side surfaces 211b of the solid conductive body 211 by means of the first fixing members 250 and the second fixing members 260. The first fixing members 250 can be fixed to the upper cover 230 by means of a plurality of screws (not shown) and respectively fix the circuit boards 220 to the side surfaces 211b of the solid conductive body 211, and the second fixing members 260 can be fixed to the lower cover 240 by means of a plurality of screws (not shown) and respectively fix the circuit boards 220 to the side surfaces 211b of the solid conductive body 211. In addition, each of the first fixing members 250 can be in electrical contact with the first grounding pads 221 on the front surface of the corresponding circuit board 220, and each of the second fixing members 260 can be in electrical contact with the second grounding pads 223 on the front surface of the circuit board 220.

[0029] The operation of the power splitter combiner 200 of this embodiment is described below. When an external signal is transmitted to the signal receiving end 213 of the power splitter combiner 200, the external signal is split into a plurality of sub-signals through the first resonance channels C1, and each sub-signal is then transmitted to the corresponding circuit board 220 (which is configured at the end of the corresponding first resonance channel C1) through the corresponding first resonance channel C1. Then, each sub-signal is amplified by the power amplifier element 228 on the corresponding circuit board 220 and then transmitted to the corresponding second resonance channel C2. Furthermore, these sub-signals are combined at the signal transmitting end 215 through the second resonance channels C2, and then the combined signal is transmitted by the signal transmitting end 215.

[0030] Based on the above, the power splitting and combining device of the embodiment of the present invention has at least one of the following advantages. The power splitting and combining device having a resonant body can split the power of the received electromagnetic wave signal, amplify it individually, and then combine it to complete the power amplification of the electromagnetic wave signal. Therefore, compared with the prior art, the predetermined power of each power amplifying element of the power splitting and combining device of the embodiment of the present invention can be smaller, and the temperature of each power amplifying element during operation will be lower, so that it is not easy to overheat and thus its operating life can be extended. In addition, power amplifying elements with lower power are usually not product items subject to export control and are easier to obtain.
