Detailed Implementation

[0034] The present application is described in detail below with reference to the embodiments, but the present application is not limited to these embodiments.

[0035] See Figure 1-3 An insulator vertical transition T-assembly, characterized in that it comprises:

[0036] A double-cavity structure, wherein one side of the double-cavity structure is a first cavity 1 and the other side is a second cavity 2. A connecting hole 3 is provided on the double-cavity structure, and the connecting hole 3 is used to install an insulator vertical transition structure. The insulator vertical transition structure connects the first cavity 1 and the second cavity 2.

[0037] Each of the two-sided cavity structures is provided with an RF input interface 4 and an RF output interface 5 at one end. The RF input interface 4 is connected to one end of the insulator vertical transition structure, and the other end of the insulator vertical transition structure is connected to the RF output interface 5, which is used to isolate the first cavity 1 and the second cavity 2 to prevent signals from interfering with each other.

[0038] The second cavity 2 integrates a radio frequency circuit. The other end of the vertical transition structure of the insulator is connected to the input terminal of the radio frequency circuit, and the output terminal of the radio frequency circuit is connected to the radio frequency output interface 5.

[0039] Specifically, the component connects the first cavity 1 and the second cavity 2 via an insulator vertical transition structure. Utilizing its isolation characteristics, the two cavities are separated to prevent signal interference. After receiving a signal, the RF input interface 4 transmits it through the insulator vertical transition structure to the RF circuitry within the second cavity 2. The processed signal is then output through the RF output interface 5, achieving stable signal transmission and effective isolation. The second cavity 2 integrates RF circuitry capable of specific processing and modulation of the input signal, such as amplification, filtering, and frequency conversion, to meet diverse application requirements. This enhances the component's functionality and flexibility. The double-cavity structure design provides two independent cavities that can accommodate different circuits or components, improving space utilization and integration. It also facilitates heat dissipation and electromagnetic shielding, enhancing the component's performance and reliability. The connection hole 3 is used to install the insulator vertical transition structure, making installation more convenient and secure, and facilitating subsequent maintenance and replacement. The RF input interface 4 and RF output interface 5 are located at one end of the double-cavity structure, facilitating connection and communication with other devices. A well-designed interface layout makes the components easier to use and reduces signal loss during transmission.

[0040] The radio frequency circuit includes:

[0041] Receiver 6;

[0042] A low-noise amplifier 7, the input terminal of which is connected to the receiver 6, is used to amplify the radio frequency signal received by the receiver 6;

[0043] Temperature compensator 8, the input terminal of which is connected to the output terminal of the low noise amplifier 7, is used to realize temperature compensation of the radio frequency signal;

[0044] A power divider group, the input terminal of which is connected to the output terminal of the temperature compensator 8, is used to split the radio frequency signal into a first radio frequency signal, a second radio frequency signal, a third radio frequency signal, a fourth radio frequency signal, a fifth radio frequency signal, a sixth radio frequency signal, a seventh radio frequency signal, and an eighth radio frequency signal;

[0045] An output processing channel, the input of which is connected to the output of the power divider group, is used to process and output the first, second, third, fourth, fifth, sixth, seventh, and eighth radio frequency signals respectively.

[0046] The output end of the output processing channel is connected to the radio frequency output interface 5.

[0047] Specifically, receiver 6, as the input to the radio frequency (RF) signal, is responsible for receiving RF signals from the outside and is the starting point for signal acquisition in the entire RF circuit. Its performance directly affects the quality of subsequent signal processing. Low-noise amplifier 7 amplifies the weak RF signal received by receiver 6 while minimizing noise introduction. During signal amplification, techniques such as negative feedback are used to suppress noise amplification and improve the signal-to-noise ratio. During signal transmission, the signal attenuates with increasing distance; low-noise amplifier 7 enhances the signal strength, enabling effective processing by subsequent circuits. Since the performance of electronic components in the RF circuit changes with temperature, temperature compensator 8 compensates for the temperature of the output signal of low-noise amplifier 7, ensuring signal stability under different temperature conditions. An internal temperature sensor monitors the ambient temperature in real time and adjusts the signal accordingly based on a preset temperature-compensation curve. This improves the environmental adaptability of the RF circuit, ensuring normal operation and stable signal output under various temperature conditions. The power divider divides the RF signal output from temperature compensator 8 into eight equal paths, forming the first to eighth RF signals. Common power dividers include Wilkinson power dividers and branch-line couplers, with the appropriate type selected based on specific requirements. This provides the foundation for subsequent multi-channel signal processing, allowing corresponding RF signals to be processed simultaneously by their respective processing channels, thus improving the system's parallel processing capabilities. The output processing channels process the eight RF signals output from the power divider group before outputting them. The processing may include filtering, amplification, modulation, and other operations to meet different application requirements. Each output processing channel can also be independently designed and configured to achieve different signal processing functions based on specific applications. This enables personalized processing and output of RF signals, allowing the entire RF circuit to adapt to complex application scenarios.

[0048] It is worth noting that after receiving the RF signal, receiver 6 transmits it to low-noise amplifier 7 for amplification. The amplified signal then enters temperature compensator 8 for temperature compensation. The compensated signal enters power divider group and is split into eight paths. Finally, each path is processed by the output processing channel and output through RF output interface 5. These components cooperate to complete the reception, amplification, compensation, splitting, and processing of the RF signal. For example, the output signal quality of low-noise amplifier 7 directly affects the compensation effect of temperature compensator 8, and the splitting accuracy of power divider group determines whether the signal strength received by each output processing channel is uniform.

[0049] The power divider group includes:

[0050] The first power divider 9 has its input terminal connected to the output terminal of the temperature compensator 8, and is used to split the radio frequency signal into radio frequency signal one and radio frequency signal two.

[0051] The second power divider 10 and the third power divider 11 are used to split the first radio frequency signal into the third radio frequency signal and the fourth radio frequency signal; the third power divider 11 is used to split the second radio frequency signal into the fifth radio frequency signal and the sixth radio frequency signal.

[0052] The fourth power divider 12, the fifth power divider 13, the sixth power divider 14, and the seventh power divider 15 are configured as follows: the fourth power divider 12 is used to split the radio frequency signal three into a first radio frequency signal and a second radio frequency signal; the fifth power divider 13 is used to split the radio frequency signal four into a third radio frequency signal and a fourth radio frequency signal; the sixth power divider 14 is used to split the radio frequency signal five into a fifth radio frequency signal and a sixth radio frequency signal; and the seventh power divider 15 is used to split the radio frequency signal six into a seventh radio frequency signal and an eighth radio frequency signal.

[0053] The output processing channel includes an attenuator 16, a first amplifier 17, a self-test combiner, a phase modulator 18, and a transmitter 19 connected in sequence. It is used to process the radio frequency signals of different branches and output the first radio frequency signal, the second radio frequency signal, the third radio frequency signal, the fourth radio frequency signal, the fifth radio frequency signal, the sixth radio frequency signal, the seventh radio frequency signal, and the eighth radio frequency signal, respectively.

[0054] The attenuator 16 is connected to the fourth power divider 12, the fifth power divider 13, the sixth power divider 14 or the seventh power divider 15 via a controller, and the output of the phase tuner 18 is connected to the radio frequency output interface 5.

[0055] Specifically, the first power divider 9 splits the RF signal output from the temperature compensator 8 into two, forming RF signal one and RF signal two, laying the foundation for subsequent multi-stage splitting. The second power divider 10 and the third power divider 11 further split RF signal one and RF signal two, respectively, generating two new RF signals, namely RF signal three and RF signal four, and RF signal five and RF signal six, realizing two-stage signal splitting. The fourth power divider 12, the fifth power divider 13, the sixth power divider 14, and the seventh power divider 15 perform three-stage splitting of RF signal three, RF signal four, RF signal five, and RF signal six, respectively, ultimately forming eight independent RF signals, namely RF signal one to RF signal eight, meeting the requirements of multi-channel signal processing. The controller uses a multi-functional chip of model G4505B06 (Chengchang Technology).

[0056] The attenuator 16 is connected to the fourth power divider 12, the fifth power divider 13, the sixth power divider 14, or the seventh power divider 15 via a controller. It adjusts the amplitude of the input RF signal to ensure it remains within a suitable level range during subsequent processing, preventing excessive signal strength from saturating or distorting subsequent circuits. The first amplifier 17 amplifies the attenuated signal, increasing its strength to meet the power requirements of subsequent circuits. The self-test combiner performs self-testing and combining of the signal, ensuring signal quality and integrity, and promptly detecting and handling any anomalies. The phase modulator 18 adjusts the signal phase to meet the phase requirements of different application scenarios, improving signal transmission performance and anti-interference capabilities. The transmitter 19 serves as the final output of the output processing channel, outputting the processed signal to the RF output interface 5 for use by external devices.

[0057] It is worth noting that the RF signal output by the temperature compensator 8 first enters the first power divider 9, where it is split into RF signal one and RF signal two. Then, RF signal one and RF signal two enter the second power divider 10 and the third power divider 11, respectively, where they are further split into RF signal three, RF signal four, RF signal five, and RF signal six. Finally, RF signal three, RF signal four, RF signal five, and RF signal six enter the fourth power divider 12, the fifth power divider 13, the sixth power divider 14, and the seventh power divider 15, respectively, where they are split into eight independent RF signals. The eight independent RF signals enter their respective output processing channels, and after being processed by the attenuator 16, the first amplifier 17, the self-test combiner, and the phase modulator 18, they are output to the RF output interface 5 through the transmitter 19.

[0058] A second amplifier 20 is connected between the first power divider 9 and the second power divider 10;

[0059] A third amplifier 21 is connected between the first power divider 9 and the third power divider 11.

[0060] Specifically, by setting a second amplifier 20 and a third amplifier 21 after the first power divider 9, the split RF signal one and RF signal two are amplified separately, which can effectively improve the signal strength, compensate for the signal loss during transmission and splitting, and ensure that subsequent circuits can receive signals of sufficient strength. The amplified signals can better resist the effects of noise and interference in subsequent splitting and processing, improve the signal-to-noise ratio, and thus improve the performance and stability of the entire RF circuit.

[0061] The self-test circuit includes a coupler 22 and a detector diode 23 connected in sequence. The input terminal of the coupler 22 is connected to the output terminal of the first amplifier 17, and the output terminal of the detector diode 23 is connected to the input terminal of the phase tuner 18.

[0062] Specifically, coupler 22, acting as a signal sampling element, couples a small portion of the signal from the RF signal output by the first amplifier 17. This small portion is used for subsequent monitoring, while the majority of the signal continues to be transmitted to subsequent circuits. The design of coupler 22 ensures minimal signal loss during coupling and minimal impact on the transmission of the main signal. Detector diode 23 converts the RF signal coupled from coupler 22 into a DC voltage signal. By detecting the magnitude of this DC voltage signal, the strength of the RF signal can be indirectly reflected. The performance of detector diode 23 directly affects the accuracy and stability of signal strength detection. In selecting components, a suitable model is chosen based on the requirements of the RF signal. For example, the T component operates at a frequency of 9.41±0.2GHz with a relatively narrow bandwidth of 0.0425. Therefore, a parallel-line coupler is suitable, and the detector diode is model 2H13B (manufactured by Yaguang).

[0063] The radio frequency (RF) signal output from the first amplifier 17 enters the coupler 22. The coupler 22 couples out a small portion of the signal according to a preset coupling degree, while the majority of the signal continues to be transmitted to the circuit section outside the subsequent self-test combining circuit. The coupled RF signal enters the detector diode 23, which converts the RF signal into a DC voltage signal. The magnitude of this DC voltage signal is proportional to the strength of the RF signal. The DC voltage signal output from the detector diode 23 is transmitted to the input terminal of the phase modulator 18. The phase modulator 18 can adjust the phase of the RF signal according to the magnitude of this DC voltage signal. For example, if the detected RF signal strength is weak, the phase modulator 18 can take corresponding measures to optimize the signal phase to improve the signal transmission performance.

[0064] The radio frequency input interface 4 is connected to one end of the vertical transition structure of the insulator via a microstrip line.

[0065] The radio frequency input interface 4 is disposed on the outer wall of the first cavity 1, and the radio frequency output interface 5 is disposed on the outer wall of the second cavity 2.

[0066] Specifically, the RF input interface 4 serves as the entry point for RF signals into the circuit, typically employing standard RF connectors such as SMA or N-type for easy connection to external RF devices and the introduction of RF signals. The RF output interface 5 is the exit point for the RF signal output circuit, also using a standard RF connector to transmit the processed RF signal to subsequent devices or systems. The first cavity 1 and the second cavity 2 provide physical mounting space for various components and functional modules in the circuit, serving as protection, isolation, and shielding. The arrangement of different cavities reduces interference between signals, improving circuit performance and stability. Microstrip lines are a common type of planar transmission line, offering advantages such as small size and ease of integration; while coaxial lines may be more suitable for long-distance transmission or applications in specific environments in certain situations. This transition structure achieves a vertical transition between microstrip lines and coaxial lines, ensuring good transmission of RF signals between different transmission line types.

[0067] The vertical transition structure between the microstrip line and the insulator ensures a smooth transition of RF signals between different transmission line types, reducing signal reflection and loss, and improving signal transmission efficiency and quality. Using microstrip lines as part of the transmission line type offers advantages such as small size and light weight, making the entire circuit structure more compact and suitable for installation and use in limited spaces. The arrangement of the first cavity 1 and the second cavity 2 enables modular circuit design, facilitating circuit assembly, debugging, and maintenance. Simultaneously, isolation between different cavities reduces signal interference and improves circuit performance and stability.

[0068] There is one radio frequency input interface 4 and eight radio frequency output interfaces 5.

[0069] Specifically, the structure includes one RF input interface 4 (X9, as shown in the figure) and eight RF output interfaces 5 (X1-X8, as shown in the figure). The RF input interface 4 is connected to one end of the vertical transition structure of the insulator via a microstrip line to introduce RF signals; the eight RF output interfaces 5 are distributed on the outer wall of the second cavity 2 and are used to distribute and output the processed RF signals.
