Description

5G combiner

Technical Field

The invention relates to the technical field of 5G combiners, in particular to a 5G combiner.

Background

As the standard of digital mobile communication is gradually developed from 2G to 5G, the speed, stability and low delay of mobile communication are improved, and the used frequency is gradually expanded to a higher frequency band. In 5G devices, the frequencies used are mainly divided into two parts, sub 6G (below 6 GHz) and millimeter waves (24 GHz-52 GHz). The frequency range of signals handled by a communication system spans a very large amount. In this scenario, a communication combiner for signal synthesis has wide application, and the device may collect RF signals of a plurality of different frequencies for transmission on the same line, or transmit RF signals of a plurality of different frequencies to different branches according to different frequencies. The combined signals of various frequencies may be transmitted through an antenna in a manner that combines RF signals of multiple different frequencies in a manner that is more economical and robust than methods that utilize separate wires and antennas for each frequency band.

However, in this way, when various radio waves having a large frequency deviation are collected together, interference may occur between the radio waves. That is, the low frequency signal may be accompanied by an undesired harmonic signal, and the high frequency signal may not be normally transmitted because the harmonic signal originating from the low frequency signal interferes with the high frequency signal. Low frequency noise in the high frequency signal may also have an effect on the low frequency band signal. Unless the signal transmission line has an impedance suitable for each transmission frequency and has a high degree of isolation between the unused frequency bands, it is impossible to prevent unnecessary noise.

A 5G combiner, as shown in fig. 1-3, includes a communication component 1, where the communication component 1 includes a hexahedral housing 2, one side of the housing 2 is provided with a first frequency-dividing port 3 and a second frequency-dividing port 4, the housing 2 is provided with a combining port 5 at the opposite side of the first frequency-dividing port 3, and the combining port 5 and the first frequency-dividing port 3 are at the mutually parallel sides of the housing 2. Transmission lines such as cables may be connected to the first frequency-dividing port 3, the second frequency-dividing port 4, and the combining port 5. And the input and output signals of the first frequency division port 3 are both sub 6G frequency bands of lower frequency bands. The signals input and output from the second frequency-dividing port 4 are millimeter wave frequency bands of a higher frequency band. The case 2 is made of a material having an electromagnetic wave shielding effect, and therefore, a sealing body can be formed so that external radio wave current does not flow.

The first and second frequency-dividing

ports

3 and 4 are formed inside the housing 2 with a first path 31 and a second path 41, respectively, inside the housing 2, the first and

second paths

31 and 41 being used for propagation of radio waves. One ends of the first path 31 and the second path 41 form the same composite path 50, the composite path 50 is connected to the composite port 5, and each radio wave travels to the composite path 50 along the individual first path 31 or second path 41 and is transmitted to the outside of the case 2 through the composite port 5. The first path 31 and the second path 41 are physically isolated, form a barrier therebetween, have a high degree of isolation, and guide each radio wave passing through the first path 31 and the second path 41 to transmit a signal.

A first dielectric resonator 32 is mounted on the first path 31, the first dielectric resonator 32 functions as a band pass filter, a second dielectric resonator 42 is mounted at one end of the second path 41, and the second dielectric resonator 42 functions as a band pass filter.

The signal passing through the first frequency division port 3 is a sub 6G signal, and the signal passing through the second frequency division port 4 is a millimeter wave signal. The sub 6G signal propagates along the first path 31, the millimeter wave signal propagates along the second path 41, and the sub 6G signal and the millimeter wave signal are transmitted to the combining path 50.

The adjuster 53 may also be used to adjust the degree of isolation between the first path 31 and the second path 41.

The first conductor 33 is connected between the first dielectric resonator 32 and the combiner 52, the first dielectric resonator 32 and the combiner 52 are connected in a short circuit, the second conductor 43 is connected between the second dielectric resonator 42 and the combiner 52, the second conductor 43 has a function of transmitting signals, the second dielectric resonator 42 and the combiner 52 are connected in an open circuit, and signal transmission is realized by coupling.

Principle analysis: among all impedance components of the radio wave transmission path, when the inductance component is high, a signal having a low radio wave frequency easily passes, and when the capacitance component is high, a low frequency radio wave is difficult to pass, and conversely, when the inductance component is high, a high frequency signal is difficult to pass, and when the capacitance component is high, a sub 6G signal of the first path 31 corresponds to a relatively low frequency band in a short circuit in which the inductance component is high, and in the transmission line, the inductance component is relatively high and the capacitance component is low, so that the low frequency signal is relatively easy to pass, while having a good suppression effect on harmonic components in the signal; the millimeter wave signal in the second path 41 corresponds to a relatively high frequency band in an open connection with a high capacitance component, and in this transmission line, the inductance component in the impedance component is relatively low and the capacitance component is high, so that a high frequency signal passes through relatively easily and a good suppression effect is provided for low frequency noise in the signal.
