Technical Field
[0001] This application relates to the field of electrical variable measurement, and in particular to a device for testing the output power of a solid-state microwave source. Background Technology

Testing the output power of solid-state microwave sources is a key step in ensuring their performance, reliability, and application compatibility.

[0020] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0021] Figure 1 This is a block diagram of a solid-state microwave source output power testing device provided in an embodiment of this application. Detailed Implementation
[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0023] The output power of a solid-state microwave source directly affects its effective range and signal strength, and it can be applied in fields such as communications, radar systems, and industrial heating.
[0024] In the field of communications, when a solid-state microwave source is used as the local oscillator of the transmitter, insufficient power will lead to a shortened signal transmission distance, a reduced signal-to-noise ratio, or even an inability to penetrate obstacles (such as the millimeter-wave transmission of 5G base stations, which has extremely high requirements for power consistency).
[0025] In radar systems, the transmission power determines the detection range (in the radar equation, the detection range is proportional to the power to the power of 1 / 4). Power fluctuations can lead to a decrease in target detection sensitivity, resulting in missed detections or false detections.
[0026] In industrial heating scenarios, insufficient power can lead to low heating efficiency and fail to meet the temperature requirements of material processing (such as microwave sintering).
[0027] During the manufacturing process of solid-state microwave sources, output power may vary due to device process deviations (such as semiconductor material doping concentration and packaging parasitic parameters). Power testing can eliminate substandard devices (such as products below the lower limit of the specification sheet) to prevent them from entering the next level of the system; it can also classify them by power level (such as grade marking) to facilitate matching design during subsequent module integration (such as cascading matching of power amplifiers).
[0028] Therefore, in the production of solid-state microwave sources, it is necessary to have an efficient and convenient way to test their output power in order to ensure the quality of the solid-state microwave sources.
[0029] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] In one exemplary embodiment, such as Figure 1 As shown, a solid-state microwave source output power testing device is provided, including a power supply module 101, a mechanical adjustment component 102, and a light-emitting indicator component 103.
[0031] The power module 101 is connected to the power supply terminal of the solid-state microwave source 100, the mechanical adjustment component 102 is connected to the control terminal of the solid-state microwave source 100, and the light-emitting indicator component 103 is connected to the output terminal of the solid-state microwave source 100.
[0032] The power module 101 is used to supply power to the solid-state microwave source 100.
[0033] The power supply module 101 that powers the solid-state microwave source 100 needs to provide stable, low-noise power according to its device type, power level, and application scenario, while meeting efficiency, reliability, and electromagnetic compatibility requirements. The power supply module 101 can adopt a DC power supply system, a high-voltage power supply device, an adjustable power supply system, etc.
[0034] Among them, the DC power supply system is suitable for low-power solid-state microwave sources (such as millimeter-wave oscillators and small-signal amplifiers) or scenarios with extremely high noise requirements (such as precision measurement and communication local oscillators). Its input stage uses an AC-DC adapter or battery (such as a 5V / 12V adapter for laboratory use and a lithium battery for portable devices), which is rectified and filtered to convert to DC voltage; the voltage regulator circuit uses a linear regulator to achieve voltage regulation by adjusting the transistor voltage drop, which is suitable for microwave sources that are sensitive to noise (such as HEMT oscillators, where power supply noise directly affects phase noise); the voltage regulator circuit can also use a switching regulator to control the switching of the power transistor through a pulse width modulation signal, which is often used in modules with high noise tolerance.
[0035] High-voltage power supply units are suitable for high-power solid-state microwave sources. They provide tens to hundreds of volts via a high-voltage DC power supply, often employing a switching power supply topology, along with high-voltage filter capacitors to avoid the risk of breakdown.
[0036] Adjustable power supply systems are suitable for solid-state microwave sources that require dynamic adjustment of output power (such as power control in communication systems and adaptive transmission in radar). The adjustment methods include voltage regulation and modulation. Voltage regulation controls output power by changing the bias voltage, requiring the power supply device to support linear adjustment from 0 to the rated voltage, and employing a digital-to-analog converter for digital control. Current modulation is for current-driven devices, achieving power regulation by controlling the bias current; the power supply device must have constant current source functionality.
[0037] In a specific application example, the power module 101 is a power adapter.
[0038] The mechanical adjustment component 102 is used to adjust the output power of the solid-state microwave source 100.
[0039] In a specific application example, the mechanical adjustment component 102 is a knob, slider, or lever.
[0040] The related solid-state microwave source 100 uses operation buttons or a touch screen on the operation panel and a circuit board to control the output power of the solid-state microwave source 100 through voltage changes. The operation panel and circuit board are expensive and have high requirements for the operating environment. This application directly adjusts the output power of the solid-state microwave source 100 mechanically (by a knob), which is low-cost and easy to operate.
[0041] Specifically, this application directly changes the power parameters through the mechanical rotation of a knob. Users can quickly adjust the power by adjusting the amplitude and direction of their hand movements, without needing to memorize complex menu logic or button combinations. For example, rotating clockwise increases the power, and rotating counterclockwise decreases the power. This direct "action-feedback" correspondence aligns with human instinctive operating habits, making it particularly suitable for scenarios requiring rapid adjustments (such as experimental debugging and on-site emergency power calibration). Moreover, the knob typically corresponds to an analog signal output (such as potentiometer adjustment), resulting in continuous and smooth power changes. Users can instantly observe the real-time changes in the neon tube's brightness by rotating the knob, leading to high adjustment efficiency.
[0042] Physical knobs have a simple structure, consisting mostly of mechanical parts, with no exposed electronic screens or sensitive circuits. This provides superior dustproof, waterproof, and vibration-resistant capabilities, making them suitable for harsh environments such as industrial sites, outdoor operations, and high humidity or dust levels. The mechanical failure rate of knobs is far lower than that of electronic components in control panels (such as touchscreens, microcontrollers, and button modules). Control panels may malfunction due to software crashes, poor button contact, or screen display problems, leading to adjustment failures. Even if knob adjustments malfunction (such as a loose knob), repair is simpler (simply replace the mechanical parts), and there are no software compatibility issues, resulting in greater long-term stability.
[0043] Knob adjustments allow for "blind operation" through tactile positioning (such as scale markings and damping on the knob), eliminating the need for users to focus their gaze on the control panel. This is particularly suitable for scenarios requiring simultaneous observation of other equipment statuses (such as monitoring oscilloscope waveforms and adjusting power in microwave experiments). Control panel adjustments, on the other hand, typically require visual confirmation of menu options or input of values, which distracts the user and can potentially impact efficiency.
[0044] The light-emitting indicator 103 is used to detect the output power of the solid-state microwave source 100.
[0045] In one specific application example, the luminous indicator 103 includes a contactless applicator and a neon tube. The contactless applicator is connected to the output terminal of the solid-state microwave source 100, and the neon tube is located in front of the contactless applicator. Specifically, the contactless applicator is connected to the output terminal of the solid-state microwave source 100 via a coaxial cable.
[0046] In this application, the light-emitting indicator 103 determines the magnitude change of the output power of the solid-state microwave source 100 based on the brightness change of the neon tube.
[0047] The essence of non-contact applications is to extract a small portion of microwave energy from the main transmission line (such as a waveguide or coaxial cable) through electromagnetic induction or field distribution coupling, without directly contacting the main power path, thus avoiding affecting the power transmission characteristics of the original system. Its principle is similar to a "directional coupler," utilizing the electromagnetic field distribution around the transmission line to guide part of the energy to the detection end through coupling structures (such as coupling loops, pinholes, or branch lines).
[0048] In one specific instance, the contactless applicator is a Tesla coil or a microwave coil.
[0049] A neon tube is a sealed glass tube filled with neon gas, typically containing two electrodes. When the applied electric field strength exceeds the ionization threshold of neon gas, the neon molecules are excited and ionized, producing a glow discharge phenomenon: microwave coupling energy creates a potential difference across the neon tube, or induces a current inside the tube through the electric field. When the electric field strength is sufficient, free electrons in the neon gas are accelerated, colliding with neon atoms and ionizing them, releasing photons and producing an orange-red glow. The greater the microwave power coupled to the neon tube, the stronger the generated electric field strength, the higher the degree of ionization, and the more obvious the glow brightness. Therefore, the power can be qualitatively judged by observing the glow brightness.
[0050] This application utilizes a non-contact power detection scheme with a neon tube to achieve intuitive qualitative detection of the output power of a solid-state microwave source 100 through "electromagnetic field coupling + gas discharge". The scheme is simple in structure and low in cost.
[0051] In a specific example, the power module is a power adapter, the mechanical adjustment component is a knob, and the luminous indicator components include a contactless applicator and a neon tube. First, connect the power supply terminal of the solid-state microwave source to the power adapter and the control terminal to the knob. Connect the output terminal of the solid-state microwave source to the contactless applicator via a coaxial cable. Place the neon tube in front of the contactless applicator. During use, the power adapter provides the required voltage to the solid-state microwave source. Use the knob to adjust the output power of the solid-state microwave source and observe whether the neon tube in front of the contactless applicator lights up. A lit neon tube indicates power output, and the change in the brightness of the neon tube determines the change in the power output of the solid-state microwave source; the higher the brightness of the neon tube, the greater the power.
[0052] In summary, the solid-state microwave source output power testing device provided in this application has low material costs, simple testing methods, and low requirements for the testing environment, thus solving the problems of complex and expensive traditional solid-state microwave source power testing.
