[0030] The present invention will be further described below in conjunction with the accompanying drawings:

[0031] like Figure 1A rapid development kit of a microwave power amplifier is shown, comprising a microwave driver module 1, a cable 2 and a microwave amplification module 3. The microwave driver module 1 receives a low-power microwave signal at its input end, and its output end is connected to the input end 3 of the microwave amplification module through the cable 2; the microwave amplification module 3 is connected to the output end of the microwave driver module 1 at its input end through the cable 2, and its output end transmits a high-power microwave signal. The microwave power amplifier can be constructed by two standard module circuits, namely, a microwave driver module and a microwave amplification module. The two module circuits have uniform dimensions and interfaces, and a microwave power amplifier circuit can be constructed. The constructed microwave power amplifier circuit can be tested in different environments.

[0032] As a further improvement of the above technical solution, the microwave driving module 1 includes a feeding unit 7, a connecting unit 5, a driving circuit unit 6, a functional circuit unit 4 and a driving circuit standard housing 8 with unified appearance and ports; the driving circuit unit 6, the functional circuit unit 4, the connecting unit 5 and the feeding unit 7 are installed in the driving circuit standard housing 8 by pan head screws. The input end of the feeding unit 7 is connected to an external power supply, and the output end is connected to the driving circuit unit 6; the driving circuit unit 6 is connected to the functional circuit unit 4 and the connecting unit 5 according to the circuit scheme. The functional circuit unit 4 includes any one or more combinations of attenuation circuits or filtering circuits. The connecting unit 5 is used for transition connection between different circuit units, and adopts a microstrip transition circuit unit with unified interface characteristics and different directions or lengths. The feeding unit 7 can include a variety of different voltage conversion circuits, which are connected to the power supply end of the driving circuit unit 6 through metallized through-hole welding wires.

[0033] Specifically, the feed unit 7 provides a suitable power supply for the driving circuit unit 6, and its input end is connected to an external power supply. It may include a variety of different voltage conversion circuits to meet the different power supply requirements of the driving circuit, and is connected to the power supply end of the driving circuit unit 6 through a metallized through-hole welding wire. Since the driving circuit unit may require a specific voltage level and a stable power supply, different application scenarios or circuit schemes may have different requirements for the power supply, so a variety of voltage conversion circuits are designed to improve versatility. The feed unit 7 solves the problem that the power supply part of the driving circuit needs to be redesigned due to different power supply requirements, improves the versatility and scalability of the module, and enables the power supply to be quickly adapted in different applications; thus, different voltage conversion circuits can be easily switched in the same standard housing, and a microwave driving module that adapts to a variety of power supply requirements can be quickly constructed, reducing the extension of the development cycle due to power adaptation issues.

[0034] The connection unit 15 is used for transition connection between different circuit units. It adopts microstrip transition circuit units with unified interface characteristics, directions or different lengths to ensure stable and low-loss transmission of signals between units. In complex microwave circuits, the interface and signal transmission requirements of different functional circuit units may be different. The unified interface characteristics facilitate the rapid construction and replacement of circuit units, and microstrip lines with different directions and lengths can meet the needs of different layouts and signal transmission paths. The connection unit 15 uses the characteristics of the microstrip line and designs its width, length and direction according to electromagnetic theory to control the impedance matching, transmission delay and other parameters of the signal to ensure signal quality. The connection unit 15 solves the problems of difficult connection between different circuit units, unstable signal transmission, and signal reflection and loss caused by mismatched connection, and improves the convenience of module assembly and circuit performance; thus, the circuit layout and signal transmission path can be quickly adjusted, and the performance of the entire microwave drive module can be optimized by simply replacing different microstrip transition circuit units of the connection unit 15, such as improving the bandwidth and phase characteristics of the signal.

[0035] The driving circuit unit 6 is used to drive and amplify the input microwave low-power signal and other core processing. It is connected to the functional circuit unit 14 and the connection unit 15 according to the circuit scheme to realize the specific processing function of the signal. The driving circuit unit 6 is the core functional part of the microwave driving module. According to the overall design requirements of the microwave power amplifier, a special driving circuit is required to increase the signal power and pre-process the signal to meet the input requirements of the subsequent microwave amplification module. Based on the principle of microwave amplification circuit, suitable transistors or integrated circuit chips are used to design the amplifier's amplification factor, input and output impedance matching, bias circuit, etc. to achieve effective amplification and processing of microwave signals. The driving circuit unit 6 realizes the preliminary amplification and processing of the microwave low-power signal, so that it can be better connected with the microwave amplification module, solves the transition problem of the signal from weak to being effectively amplified, and improves the signal processing capability of the entire power amplifier system. By selecting driving circuit units 6 with different performances, the gain, bandwidth and other characteristics of the microwave driving module can be flexibly adjusted, and different application requirements can be quickly adapted without changing the overall module structure.

[0036] Functional circuit unit 14 includes any one or more combinations of attenuation circuits or filtering circuits, which are used to perform auxiliary processing such as attenuation and filtering on the signal to improve the signal quality or meet specific signal spectrum requirements. In microwave signal processing, it is often necessary to adjust the amplitude and frequency components of the signal. The attenuation circuit can control the signal strength, and the filtering circuit can remove unnecessary frequency components to improve the purity and stability of the signal. The attenuation circuit realizes proportional attenuation of the signal based on principles such as resistor networks; the filtering circuit realizes the screening of specific frequency signals based on filter design theory, such as using structures such as LC filters and microstrip filters. Functional circuit unit 14 solves the problems of excessive signal amplitude and disordered frequency components that may occur during the transmission and processing of microwave signals, improves the quality and stability of the signal, and enables subsequent circuits to better process the signal. By flexibly combining different attenuation and filtering circuits, the signal processing function of the microwave driver module can be quickly customized for special signal interference or application scenarios, thereby improving the adaptability and anti-interference ability of the module.

[0037] The standard housing 8 of the driving circuit is used to provide a unified installation platform for the driving circuit unit 6, the functional circuit unit 4, the connection unit 5 and the feeding unit 7, and each unit is fixed therein by a pan head screw to ensure the mechanical stability and electrical connection reliability of each component, and at the same time, the appearance and port standards of the entire microwave driving module are specified. In order to realize the standardized design and rapid assembly of the microwave driving module, it is convenient to use and replace in different application scenarios, and improve the production efficiency and versatility of the module. According to the mechanical structure design principle, the present invention designs a suitable housing shape, size and internal layout, considers the installation position, heat dissipation requirements, electrical isolation and other factors of each circuit unit, and ensures that the housing can protect the internal circuit and facilitate the connection and maintenance of each unit. The technical problem solved: the problems of irregular installation of each component of the microwave driving module, poor mechanical stability and difficulty in integration and replacement due to the non-uniform appearance are solved, and the production efficiency and maintainability of the module are improved. The standard housing 8 of the driving circuit can easily integrate microwave driving modules with different functions into a larger system. Due to the unified appearance and port, the difficulty and cost of system integration are reduced, and it is conducive to the mass production and quality control of the module.

[0038] Therefore, through the above design, microwave driving modules with different frequencies, gains and other functions can be realized by installing different circuit units with uniform dimensions in a standard driving circuit standard housing. Based on the existing standard circuit units of dozens of commonly used devices, microwave driving modules with specific frequencies and gain functions can be quickly realized.

[0039] As a further improvement of the above technical solution, the microwave amplification module 3 includes a feed unit 2 12, a connection unit 2 10, a microwave power tube unit 11, a functional circuit unit 2 9 and a power tube circuit standard housing 13 with unified appearance and ports; the microwave power tube unit 11, the functional circuit unit 2 9, the connection unit 2 10 and the feed unit 2 12 are all installed in the power tube circuit standard housing 13 by pan head screws. The input end of the feed unit 2 12 is connected to an external power supply, and the output end is connected to the microwave power tube unit 11; the microwave power tube unit 11 is connected to the functional circuit unit 2 9 and the connection unit 2 10 according to the circuit scheme. The functional circuit unit 2 9 includes any one or more combinations of input isolators and output isolators. The connection unit 2 10 is used for transition connection between different circuit units, and adopts a microstrip transition circuit unit with unified interface characteristics, different directions or lengths.

[0040] The feed unit 2 12 includes a 28V drive circuit, a 28V negative voltage conversion circuit, and a negative voltage protection circuit; the feed unit 2 12 is connected to the power supply end of the microwave power tube unit 11 through a metallized through-hole welding wire. The power tube circuit standard housing 13 includes M2 and M2.5 through-holes and a standard installation slot for the power tube.

[0041] Specifically, the feed unit 2 12 is used to provide a suitable power supply for the microwave power tube unit 11, including a 28V drive circuit, a 28V negative voltage conversion circuit, a negative voltage protection circuit, etc., and is connected to the power supply end of the microwave power tube unit 11 through a metallized through-hole welding wire to meet the special power supply requirements of the microwave power tube. Microwave power tubes usually require a higher voltage and a specific bias voltage (such as negative voltage) to work normally, and a protection circuit is required to prevent abnormal conditions such as overvoltage and overcurrent from damaging the power tube, so a feed unit with multiple functions is designed. The 28V drive circuit provides the main working voltage of the power tube, the 28V negative voltage conversion circuit uses the principle of charge pump or transformer to generate negative voltage, and the negative voltage protection circuit protects the power tube by monitoring parameters such as voltage and current, and using overvoltage and overcurrent protection chips or circuit structures. The feed unit 2 12 solves the problems of complex power supply of microwave power tubes, susceptibility to power supply fluctuations, and lack of protection, improves the stability and reliability of the operation of microwave power tubes, and extends their service life. By designing a feed unit 12 integrating multiple functions, it is possible to quickly provide an adaptive power supply for different types of microwave power tubes. When replacing the power tube, there is no need to redesign the power supply part, thereby improving the flexibility and maintainability of the microwave amplification module.

[0042] The connection unit 2 10 is similar to the connection unit 1 5, and is used for transition connection between different circuit units. It adopts a microstrip transition circuit unit with a unified interface feature, different direction or length to ensure stable transmission of signals between microwave power tube unit 11, functional circuit unit 2 9 and other units. In the microwave amplification module, it is also necessary to solve the connection and signal transmission problems between different circuit units. The unified interface facilitates the rapid construction and adjustment of the circuit, and the microstrip transition circuit can be optimized according to the internal layout of the module and the signal transmission requirements. Based on the microstrip line transmission theory, the present invention designs appropriate microstrip line parameters to achieve impedance matching and low-loss transmission of the signal, ensuring the effective transmission of microwave signals between the units; solves the standardization of the internal circuit connection of the microwave amplification module and the optimization of signal transmission, improves the assembly efficiency of the module and the signal transmission quality, and reduces the signal distortion and power loss caused by the connection problem. By adjusting the microstrip line parameters of the connection unit 2 10, such as the length and width, the input and output impedance matching of the microwave amplification module can be fine-tuned to a certain extent, and the gain flatness and bandwidth characteristics of the entire power amplifier can be improved.

[0043] The microwave power tube unit 11 is used to amplify the input microwave signal with high power. It is the core component of the microwave amplification module. It is connected to the functional circuit unit 2 9 and the connection unit 2 10 according to the circuit scheme, and amplifies the input microwave low-power signal into a high-power signal output. The main function of the microwave power amplifier is to achieve power amplification. The microwave power tube has high power processing capability and microwave signal amplification characteristics, and is a key device to achieve this function. The present invention is based on the semiconductor physical properties of the microwave power tube, such as the amplification principle of the transistor, and through the reasonable design of the bias circuit, input and output matching network of the power tube, the power tube works in the optimal amplification state to achieve efficient amplification of the microwave signal. The microwave power tube unit 11 realizes high-power amplification of the microwave signal, meets the demand for microwave high-power signals in practical applications, such as power amplification requirements in radar transmitters, communication base stations and other systems. By selecting microwave power tube units 11 of different types and parameters, the output power, gain and efficiency of the microwave amplification module can be quickly adjusted to meet the application requirements of different power levels, and to a certain extent, the peripheral circuits of the power tube can be optimized to further improve its performance, such as improving linearity and stability.

[0044] Functional circuit unit 29 includes any one or more combinations of input isolators and output isolators, which are used to isolate input and output signals, prevent the influence of reflected waves on the front and rear circuits, and improve the stability and anti-interference ability of the circuit. In the process of microwave power amplification, signal reflection may cause damage to the power tube or degradation of circuit performance. The input and output isolators can effectively reduce the influence of reflected waves, protect the circuit and improve signal quality. The isolator is based on the non-reciprocity principle of ferrite materials, etc., so that the signal can only be transmitted in one direction, thereby blocking the reverse propagation of the reflected wave. The problem of circuit instability and easy damage of the power tube caused by signal reflection in the microwave amplification module is solved through the functional circuit unit 29, the reliability and anti-interference ability of the module are improved, and the stable operation of the entire power amplifier system is ensured. By reasonably arranging the input and output isolators, the input and output matching of the microwave amplification module can be optimized, the signal loss and power fallback caused by poor matching can be reduced, and the efficiency and gain of the entire power amplifier can be improved.

[0045] The power tube circuit standard housing 13 provides a unified installation platform for the microwave power tube unit 11, the functional circuit unit 2 9, the connection unit 2 10 and the feed unit 2 12, fixes each unit by pan head screws, specifies the appearance and port standards of the module, and includes M2 and M2.5 through holes and standard installation slots for power tubes, which are convenient for the installation and heat dissipation of the power tube. Similar to the standard housing for the drive circuit, in order to realize the standardized design and rapid assembly of the microwave amplification module, improve the production efficiency and the versatility of the module, and take into account the heat dissipation requirements and installation requirements of the microwave power tube, the present invention designs the shape, size, through hole position and heat dissipation structure of the housing according to the mechanical structure design and thermal design principles, ensures that each circuit unit is firmly installed, the electrical connection is reliable, and can effectively dissipate heat, and ensures that the power tube is within the normal operating temperature range. The power tube circuit standard housing 13 solves the problems of standardized installation, heat dissipation and appearance uniformity of various components of the microwave amplification module, improves the production efficiency, maintainability and reliability of the module, and is convenient for integration and replacement in different systems. Since the power tube circuit standard housing 13 includes a standard installation slot for the power tube, different types of power tubes can be quickly replaced for performance testing and optimization, thereby improving the adaptability and debuggability of the microwave amplification module without changing the entire module structure.

[0046] Therefore, through the above design, microwave amplification modules with functions such as different frequencies and output powers can be realized by installing circuit units with different uniform dimensions in a standard power tube circuit housing. The power tube circuit housing includes several commonly used installation slots for power tubes, so that microwave amplification modules with specific frequencies and output powers can be quickly realized.

[0047] The development method of the above-mentioned rapid development kit of microwave power amplifier is as follows:

[0048] S1. Determine the required components based on the circuit scheme.

[0049] S2. Install the existing packaged device on a standard circuit unit, where the standard circuit unit refers to a standard circuit unit of dozens of existing commonly used devices.

[0052] S5. After building the circuit, optimize the circuit solution and complete the circuit design work by testing and debugging the actual indicators of the circuit.

[0053] In summary, the microwave power amplifier rapid development kit described in the present invention, by decomposing the microwave power amplifier into two standard module circuits, namely the microwave driving module and the microwave amplification module, uses its unified dimensions and interfaces to quickly build a microwave power amplifier circuit, and conduct tests in different environments to solve the problems of deviation between the design simulation results and the actual test results, multiple rounds of design submission, etc. in the design of traditional microwave power amplifiers. The design process of traditional microwave power amplifiers is complex, and the various parts are highly correlated. Once a problem occurs in a certain link, it takes a lot of time and cost to modify and resubmit. The present invention adopts modular design to decompose the complex design process, reduce the coupling between the various parts, and improve the design efficiency and flexibility. Based on the modular design concept, the present invention divides the function of the microwave power amplifier into two relatively independent modules of driving and amplification, and each module is further refined into multiple functional units. Rapid assembly and replacement are achieved through standardized interface and shell design. Each module can be optimized separately during the test process, and then combined into a complete power amplifier for overall testing and adjustment. Since the actual circuit can be quickly built and tested in different environments, the present invention can promptly discover and correct problems in the design, avoiding errors caused by relying solely on simulation. Through standardized module design and rapid circuit construction, the present invention reduces the time wasted in multiple rounds of design and casting, and the problems in the scheme can be improved by quickly replacing the module units without redesigning the entire circuit. The present invention can quickly combine microwave drive modules and microwave amplification modules with different functions according to different application requirements, such as changing parameters such as frequency, gain, and output power, to adapt to the design requirements of various microwave power amplifiers. During the use of the product, if a module fails or needs a performance upgrade, the corresponding module can be quickly replaced, reducing maintenance costs and downtime, and improving the service life and reliability of the product.
