Description

Technical Field

[0001] The utility model relates to the field of communication technologies, and particularly relates to a power divider. Background Art

[0002] A power divider, also known as a power splitter or power distributor, is a device used to distribute the input signal power to multiple output ports. The power divider usually consists of an input port and multiple output ports. The working principle of the power divider is based on the transmission and distribution of electromagnetic waves. When the input signal passes through the power divider, the electromagnetic waves propagate on the transmission lines inside the power divider. Through specific structural designs, the electromagnetic waves are equally or unequally distributed among the output ports. The distribution ratio of the power divider can be achieved by adjusting parameters such as the length, width, and spacing of the transmission lines.

[0003] In the prior art, the actual use effect of the power divider is easily affected by the manufacturing dimensions, especially parameters such as the spacing and size of each pin. These parameters directly affect the impedance matching, signal interference and coupling, and heat dissipation performance of the power divider. For example, if the spacing between the pins of the power divider is too small, it is easy to increase the interference between signals and reduce the integrity of the transmitted signal; if the spacing between the pins is too large, it is easy to increase the length of the signal transmission path, increase the loss, and unreasonable pin sizes will affect the characteristic impedance of the transmission line and the impedance matching effect. Thus, it can be seen that the existing power divider is prone to increasing the interference between signals due to the unreasonable structural design layout of the pins, thus making it difficult to ensure the integrity of the transmitted signal and reducing the reliability of the power divider in use. The purpose of this invention is to provide a new way for the structural design layout of each pin, so as to improve the power distribution efficiency, signal integrity, and reliability in use of the power divider through reasonable size design. Summary of the Utility Model

[0005] To achieve the above purpose, the utility model provides a power divider, which includes a base, an inductance coil, and several pins.

[0029] Embodiment 1:

[0030] The present utility model provides a power divider.

[0031] In an embodiment of the present utility model, a power divider includes a base, an inductance coil, and a plurality of pins. The inductance coil is disposed on the base and electrically connected to the plurality of pins. The plurality of pins are respectively disposed on both sides of the base in a one-to-one correspondence. The plurality of pins are uniformly and spaced apart along the extending direction of the base. The distance between two adjacent pins is 1.27 ± 0.1 mm. The length dimensions of the plurality of pins are the same and are 1.4 ± 0.1 mm, and the width dimensions of the plurality of pins are the same and are 0.76 ± 0.1 mm. Among them, one pin is a signal input end, and the remaining pins are signal output ends.

[0032] Specifically, as Figures 1 to 9 shown, in a power divider of the present utility model, the base, as the main structure of the power divider, can carry the inductance coil and the pins and provide a stable support structure to ensure that the inductance coil and the plurality of pins can be firmly installed and maintain good electrical connections. Further, since the inductance coil is electrically connected to the pins, precise control of signal frequency, impedance and other characteristics can be achieved by designing the parameters of the inductance coil (such as the number of turns, diameter, etc.). In addition, by respectively disposing the plurality of pins on both sides of the base in a one-to-one correspondence, this layout helps to evenly distribute and transmit signals; and the plurality of pins are uniformly and spaced apart along the extending direction of the base, so as to effectively ensure that the signals maintain consistent attenuation and phase characteristics during the transmission process.

[0033] Understandably, in the actual use of existing power dividers, if the pin spacings of the power dividers are designed to be too compact, it is likely to lead to increased mutual interference between signals, thereby weakening the integrity of the transmitted signals; conversely, if the pin spacings are too wide, it will prolong the signal transmission path length, thereby increasing signal loss, and inappropriate pin sizes will also have an adverse impact on the characteristic impedance of the transmission line, thus reducing the efficiency of impedance matching. In a power divider of the present utility model, the spacing between two adjacent pins is 1.27 ± 0.1 mm, which can not only effectively reduce the electromagnetic interference between the pins through precise spacing control, but also ensure the electrical isolation between the pins, and this spacing also complies with common PCB layout standards, facilitating the integration and connection with other electronic components; at the same time, since the length dimensions of several pins are the same and are 1.4 ± 0.1 mm, and the width dimensions are the same and are 0.76 ± 0.1 mm, it can reduce the signal transmission loss between the pins and ensure the minimization of phase differences, effectively improving the signal transmission quality, transmission efficiency and integrity, and being reliable in use.

[0034] It is worth noting that in the actual production and manufacturing process of a power divider of the present utility model, optimization and tuning can be carried out through simulation software, and the test simulation results are Figures 6 to 9 as can be seen, and the test data is shown in the following table:

[0035] Electrical Specifications: TA = 25 °C, 0 dBm, Z0 = 50 Ω

[0036] Parameter Test Conditions Units Min Typ Max Main line Loss (Pin6 - 4) 5 - 1000 MHz dB - 0.5 1.0 Main line Loss (Pin6 - 3) 5 - 1000 MHz dB - 0.5 1.0 VSWR 5 - 1000 MHz dB - 1.0 1.5 Amplitude Unbalance 5 - 1000 MHz dB - 0.3 1.0 Phase Unbalance 5 - 1000 MHz dB - 1.0 6.0 Isolation 5 - 1000 MHz dB 16.0 22.0 -

[0037] The insertion loss of the present utility model within the frequency range of 0 to 1000 MHz is 0 to 1 dB, that is, the energy loss of the signal when passing through the present utility model is small and it can maintain a high signal strength and transmission efficiency, making the present utility model suitable for application scenarios requiring high-fidelity and low-loss signal transmission; at the same time, the voltage standing wave ratio shown by the present utility model is 0 to 1.5. Understandably, since the closer the voltage standing wave ratio is to 1, the smaller the reflection and the better the impedance matching, this indicates that the present utility model has good impedance matching performance, enabling the present utility model to not only effectively reduce the reflection of the signal, but also improve the signal transmission efficiency and power utilization rate, and is reliable in use. Additionally, obviously, the present utility model also shows low amplitude imbalance and phase imbalance as well as large isolation within the frequency range of 0 to 1000 MHz. The lower the amplitude imbalance, the smaller the error, the signal amplitudes of the pins of each output port are relatively consistent, the distortion of the signal during distribution is small, and it can maintain a high signal quality and stability; the low phase imbalance indicates that the signal can maintain a high phase consistency during distribution and synthesis, thereby ensuring the signal transmission quality and the stability of the system; the larger the isolation, the smaller the mutual influence between the pins of each output port, and thus it can effectively reduce the interference and noise during signal transmission, which is beneficial to improving the signal quality and stability, ensuring that the system can work properly and is reliable in use. In summary, the present utility model shows low insertion loss, good impedance matching performance, low amplitude imbalance and phase imbalance as well as large isolation within the frequency range of 0 to 1000 MHz, thereby making the present utility model have the characteristics of high fidelity, low loss, high stability and high accuracy, and is reliable in use.

[0038] In one embodiment, specifically, as Figure 2 shown, the length dimension of the base is 3.80 ± 0.2 mm, the width dimension of the base is 4.20 ± 0.2 mm, and the height dimension of the base is 0.55 ± 0.1 mm. Thus, not only can the base accommodate the inductance coil and pins, but also there is enough space to ensure electrical isolation and heat dissipation between components, and this dimension also conforms to the common electronic component packaging standards, thereby facilitating the integration with other electronic devices. Further, by making the height dimension of the base 0.55 ± 0.1 mm, it can ensure the compactness and light weight of the base, and at the same time provide enough space to install the inductance coil and pins, and meet the compatibility of the present utility model with other electronic components, effectively avoiding interference during the assembly process.

[0039] In one embodiment, specifically, as Figure 3 shown, the height dimension of the power splitter is 2.80 ± 0.2 mm, thereby effectively ensuring good compatibility and stability when the present utility model is integrated with other electronic devices or PCB boards.

[0040] In one embodiment, a housing is provided at the top of the inductance coil. Specifically, as Figure 1 shown, on the one hand, the inductance coil can be shielded by the housing, thereby avoiding interference of the inductance coil by the external environment, effectively preventing dust, moisture and other pollutants from entering the inside of the inductance coil and damaging the inductance coil, and further extending the service life of the power divider; on the other hand, the housing can also assist in fixing the inductance coil to ensure the stability and position accuracy of the inductance coil on the base.

[0041] The foregoing is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
