Description

TECHNICAL FIELD

[0001] The present application relates to the field of radio frequency communication and microelectronic signal processing technology, and particularly relates to a radio frequency signal processing method and system of a radio frequency transceiver chip. BACKGROUND

[0002] The radio frequency signal processing of the radio frequency transceiver chip refers to the whole process of comprehensive optimization and dynamic control of the radio frequency chip in realizing signal transmission and reception, including signal acquisition, amplification, modulation, demodulation, filtering, frequency switching and interference suppression. The core goal of the processing process is to ensure high-fidelity transmission and stable analysis of signals in multi-frequency, multi-standard and multi-scene environments. In the above technical solution, the radio frequency signal processing not only includes low-noise amplification and non-linear distortion compensation of the original signal to ensure the linearity and signal-to-noise ratio of the signal link, but also covers the process of accurately identifying and filtering out complex frequency domain interference such as adjacent channel interference and co-channel interference through dynamic spectrum sensing and frequency hopping filtering algorithm. Further, the system uses a reconfigurable radio frequency front-end architecture to realize flexible switching of multiple frequency bands (such as Sub-6GHz and millimeter wave), and monitors and adaptively adjusts the signal power, linearity and frequency domain state in real time through a signal quality feedback module, thereby constructing a closed-loop radio frequency signal processing system running through signal preprocessing-frequency domain anti-interference-multi-band adaptation, so that the radio frequency transceiver chip can continuously output high-quality and low-distortion radio frequency signals in different application environments such as communication, navigation and radar.

[0003] The prior art has the following disadvantages: In the prior art, the radio frequency transceiver chip usually relies on a waveguide structure to guide energy and control field distribution during high-frequency signal transmission. However, due to problems such as geometric asymmetry, uneven distribution of dielectric constant or assembly tolerance deviation in the internal structure design of the waveguide, an asymmetric standing wave field is easily formed in the high-frequency band. When the incident wave and the reflected wave are unevenly superimposed in a specific area, part of the high-frequency energy is trapped in the waveguide resonant cavity boundary area and repeatedly reflected, forming a local energy retention area. The trapped energy cannot be transmitted along the waveguide in time and is gradually converted into heat energy accumulated at the cavity boundary, causing the local temperature of the chip to continuously rise and forming a hidden heat spot. Under the conditions of long-time work or frequency dynamic switching, the heat spot easily triggers material thermal instability, metal interconnection layer melting and structure stress damage, and eventually causes local over-temperature burnout of the chip.

[0004] The above information disclosed in the background section is only used to enhance the understanding of the background of the present disclosure, and therefore it can include information that does not constitute prior art known to those of ordinary skill in the art. SUMMARY

[0051] Example implementations will now be described more fully with reference to the accompanying drawings. Example implementations may, however, be implemented in many different forms and should not be construed as limited to the examples set forth herein; rather, these example implementations are provided so that this disclosure will be thorough and complete, and will fully convey the scope of example implementations to those skilled in the art.

[0052] The present application provides a method for processing a radio frequency signal of a radio frequency transceiver chip as shown in Figure 1 The method for processing a radio frequency signal of a radio frequency transceiver chip comprises the following steps:

[0053] S1, performing a slow sweep operation inside the waveguide and applying a thermal disturbance, guiding energy distribution by frequency change to form a bright-dark undulating track, and extracting a standing wave shadow line from the continuous bright-dark rhythm to locate an energy gathering area;

[0054] In order to accurately locate the energy accumulation area caused by high-frequency signal coupling in the waveguide structure, the energy distribution characteristics are tested by frequency response, and the following specific embodiment is proposed, which is based on the analysis and processing of the linkage characteristics of frequency and energy spatial distribution. The specific embodiment is as follows:

[0055] An adjustable frequency sweeping signal source and a high-sensitivity detection terminal are respectively connected at both ends of the waveguide structure. The starting frequency of the frequency sweeping signal source is set to 22.5GHz, the terminal frequency is set to 27.5GHz, the frequency step is set to 50MHz, and the slow linear sweeping operation is executed. During the sweeping process, the output power is stably controlled below-10dBm to avoid high-power input causing second harmonic or nonlinear gain, and to ensure the purity and controllability of the measurement environment. At the same time, a flexible thermoluminescence film is installed on the outer wall of the waveguide cavity, which has a response spectrum in the near-infrared segment and is extremely sensitive to weak thermal disturbance. The film is uniformly attached to the outer wall of the cavity through a low-viscosity high-temperature stable adhesive, and a thermal disturbance generator is set to apply a periodic thermal disturbance through a pulse thermal stimulation signal during the sweeping process, with a thermal disturbance period of every 500MHz and a duration controlled within 30ms. In this way, the coupling between signal energy and local temperature will be accurately amplified, forming a bright-dark thermal response map in the spatial dimension.

[0056] Start the high-resolution thermal imaging unit and synchronously capture the response of the above-mentioned thermoluminescence film, with a sampling frame rate of 120 frames per second. In the image frames corresponding to different frequencies, the bright area represents temperature rise, and the dark area represents relatively stable temperature difference. By superimposing multiple continuous frequency images and comparing the bright and dark rhythm change tracks, the spatial migration path of energy with frequency change in the waveguide can be observed. Through image processing, the areas that repeatedly appear at fixed positions or have intensity mutations with frequency change are identified as local standing wave superposition areas. Further based on the intensity difference of the tracks, the bright area trend and concentration trend can be derived, and the energy accumulation band of standing wave interference is preliminarily outlined, forming a continuous thermal response shadow line, which has repeatability and stability, representing the trend path of energy coupling and residence in the waveguide cavity.

[0057] After extracting the standing wave shadow lines in the bright-dark thermal response map, select several frequency points in the representative waveband, such as 23.1 GHz, 24.5 GHz and 26.3 GHz, fix the frequency at these points and extend the sweep time to 10 seconds to enhance the thermal disturbance response amplitude. In this process, the bright band area on the thermoluminescence film will be further strengthened, and the boundary of the energy gathering path will be more clearly identifiable. After enhancing the image, perform gray scale fitting analysis, extract the gray scale line, fit the contour and brightness gradient direction, and accurately reconstruct the standing wave energy density distribution map. In this map, the energy density peak position is highly consistent with the gray scale curvature inflection point, and these positions are defined as the center axis of the high-energy area. By extending the center axis in the axial direction, the main direction of energy movement in the continuous path and the diffusion trend of the adjacent area can be identified, providing a precise spatial basis for subsequent drainage path setting.

[0058] On the basis of the reconstructed energy density map, the path corresponding to the standing wave shadow line is converted into a spatial calibration line in the physical coordinate system, and high-precision three-dimensional calibration is performed inside the waveguide cavity through a laser positioner. The calibration accuracy is controlled within ±20 microns, ensuring the accuracy of subsequent structure adjustment and additional medium layout. According to the calibration line information, a positioning identification line groove is lightly etched on the inner wall of the waveguide in a laser etching manner, with a groove depth not exceeding 20 microns, which does not affect the electromagnetic wave transmission characteristics but provides reliable positioning reference. In the actual processing of the waveguide structure, additional energy control structures can be arranged according to the groove, or used as a reference line for other fine operations, realizing the close integration of energy path identification and physical positioning. Through the above method, not only the spatial visualization and accurate calibration of the energy gathering area are realized, but also an operable and replicable engineering foundation is laid for the subsequent arrangement of energy control devices.

[0059] S2, attach a tearable micro-absorption layer to the waveguide cavity wall corresponding to the standing wave shadow line, use the selective adsorption of the micro-absorption layer surface to high-frequency energy to form a stable adsorption mark at the energy retention position to establish the drainage anchor point;

[0060] After completing the positioning of the energy gathering path, in order to realize the spatial anchoring of energy drainage, a physical identification structure with selective adsorption ability needs to be constructed in the energy residence area to provide a stable and traceable drainage starting point. The following is the specific implementation process:

[0061] Based on the spatial thermal response calibration results formed by the standing wave shadow lines on the waveguide structure cavity wall, the high-energy path is converted into an operable three-dimensional attachment area in the physical coordinate system. A microstructure composite adsorption material with frequency response selectivity is selected as the basic material of the attachment layer. The adsorption material is composed of a silicon-based controllable peeling layer and a composite elastomer with surface-embedded metal particles. The metal particles are silver-palladium alloy microspheres with a particle size of 80-120 nm, and the doping ratio is not less than 3.2 mg / cm2. The boundary standing wave effect of electromagnetic waves in the frequency range of 23-27 GHz can be strengthened. Through the laser projection auxiliary positioning device, the micro-absorption layer attachment operation is carried out along the corresponding area of the standing wave shadow line on the inside of the waveguide cavity wall, and the attachment accuracy is controlled within ±15 microns. In order to improve the stability and removability of the attached structure, the edge of the adsorption layer is pre-set with a toothed embedded groove, which can form a close but not permanent bonding critical attachment state with the inner wall of the waveguide in the micro-deformation state, so that it can be removed or adjusted without damage in the subsequent test or structure optimization stage.

[0062] After the adsorption layer is attached, the energy response in the standing wave path is excited by applying continuous fixed frequency excitation. The frequency selection is consistent with the previous frequency sweep positioning results, and the three representative frequency points of 23.5 GHz, 24.8 GHz and 26.1 GHz are preferred. The continuous excitation time is maintained for 8 seconds per point. Under this excitation condition, the energy in the waveguide is concentrated and superimposed along the path indicated by the previous standing wave shadow line. The surface of the selective adsorption material interacts with the energy standing area, producing a weak charge accumulation and local temperature rise effect that can be sensed. Through external infrared imaging equipment monitoring, it can be observed that bright spot structures appear on the surface of the adsorption layer. The distribution of the bright spots overlaps with the previous standing wave thermal response bright-dark map by more than 95%. This phenomenon indicates that the adsorption layer has successfully captured the high-frequency energy concentration area and formed a spatially stable adsorption response, providing a visual and positioning basis for subsequent energy guiding operations.

[0063] In order to make the adsorption structure not only serve as a response marker, but also as an anchor node in the energy drainage process, the adsorption layer material structure is gradient-controlled. A micro-groove structure is designed on the inside contact surface of the adsorption layer, with a groove depth of 3 microns and a spacing of 50 microns. The arrangement direction is consistent with the direction of the main energy concentration path. When high-frequency energy is concentrated in the adsorption area, the electromagnetic field produces an edge aggregation effect between the micro-grooves, making the adsorption layer boundary electric field distribution more concentrated and directional. Under this structure control, the adsorption layer not only adsorbs high-frequency energy, but also implies the energy movement trend in a physical structure way. In the energy response state, the temperature rise amplitude of the local micro-groove area along the edge of the adsorption layer reaches 3.7 degrees Celsius, while the temperature rise of the non-micro-groove area is less than 1.2 degrees Celsius, showing a secondary focusing effect of energy in the edge groove area. This effect further enhances the guiding effect of the adsorption layer on the energy drainage direction, forming a physical and energy response dual positioning structure.

[0064] On the basis of the energy absorption and the establishment of the flow trend, the adsorption layer is treated to be tearable for subsequent structural cooperation and maintenance management. A low peeling adhesive is used to adhere the edge of the adsorption layer, and the initial bonding strength is controlled in the range of 0.12 N / cm to 0.15 N / cm, and the bonding area is 15% of the total adsorption layer area. The setting ensures that the adsorption layer will not fall off during normal use, but can be uniformly pulled off in 30 seconds without damage during structural debugging, failure analysis or energy path adjustment. The edge of the adsorption layer is provided with three positioning protrusions for aligning the original physical calibration slot line when reattaching, and the repeated installation error is less than 10 microns. Through the above structural design, the adsorption layer not only forms a stable energy response mark in the energy residence area, but also has high maintainability and reusability, so that the structure has good operability and engineering stability in actual radio frequency transceiver chip testing and long-term operation.

[0065] S3, injecting a phase-reversed micro pulse to the adsorption mark position, causing the cavity energy to be phase-tracked along the adsorption mark direction and gradually move outward, thereby constructing a continuous energy flow trajectory;

[0066] After completing the physical anchoring of the energy residence area, in order to further guide the orderly outward movement of energy from the residence point, a perturbation energy pulse with directional control characteristics needs to be actively applied, so that the standing wave energy no longer stably resides in the original aggregation area, but phase shifts and path reconstructs in a specific direction, thereby forming an energy flow trajectory with control and guidance ability. The following are the specific implementation steps:

[0067] According to the standing wave shadow line marked by the adsorption structure and the adsorption mark position, a plurality of micro pulse couplers are uniformly arranged at the corresponding position outside the waveguide cavity for injecting directional micro pulse interference signals into the cavity. The micro coupler adopts a double-layer stacked ceramic piezoelectric excitation structure, the structure shell thickness is not more than 1 mm, the length is parallel to the waveguide cavity, and the length is controlled within 15 mm. The coupler is fixed to the waveguide outer wall by conductive adhesive, and the injection direction is configured with a reverse micro inclination angle to the energy residence path, and the inclination angle is set to be between 3 degrees and 7 degrees. The excitation frequency is set to be a phase-reversed value adjacent to the energy residence frequency band but with a slight offset. For example, for the 24.8 GHz residence frequency point, the phase-reversed pulse frequency can be set to 24.65 GHz, and the power is controlled between -13 dBm and -11 dBm to avoid local overpressure in the cavity caused by energy superposition.

[0068] After the micro-pulse coupler is laid out, multiple rounds of synchronous excitation tests are performed, with each round of pulse width controlled at 3 microseconds and periodic emission frequency at 30 times per second, and the temperature distribution and electromagnetic response of the adsorbed mark area and its adjacent area are monitored under the condition of continuous pulse emission. According to the measured data, after 10 seconds of injection, it can be observed that the bright spot of the original adsorption area boundary gradually shifts to one side, and the displacement direction of the bright spot is consistent with the injection direction set by the coupler, and the maximum displacement distance is about 3.2 millimeters. This phenomenon shows that the original standing wave energy in the cavity is partially directionally dragged due to the influence of phase disturbance, and gradually shifts along the preset path. In order to improve the stability of the flow effect, the pulse emission time difference between the adjacent two couplers is adjusted synchronously in the second round of excitation, and the delay between each pair is set to 0.5 microseconds, forming a rhythmic phase intervention sequence. This method can establish a weak but continuous phase promotion gradient in the energy traction path, effectively improving the continuity of energy movement.

[0069] In order to enhance the repeatability and directionality control of the flow path, the material structure of the edge of the adsorbed mark area is cooperatively regulated. The edge of the adsorption layer has a micro-slot structure in the previous structure design, and now the slot depth is adjusted from 3 microns to 5 microns through local hot pressing treatment, and conductive polymer particles with a particle size of about 200 nanometers are introduced at the bottom of the slot, with a conductivity higher than 120 Siemens per centimeter. This treatment changes the local electromagnetic environment at the microscale, allowing the externally injected phase-reversal pulse to produce a stronger edge reconstruction effect when it contacts the edge of the adsorbed mark, thereby causing nonlinear phase slip of the energy near the contact point. This slip gradually propagates along the extension direction of the adsorption layer, eventually causing the overall phase structure of the entire energy standing area to shift, creating an energy traction path that starts at the adsorbed mark and extends along the slot line. This path has high directional consistency and frequency response matching, and can maintain stable expansion under continuous injection of pulses.

[0070] After the energy traction path is initially formed, temperature sensor groups are arranged equidistantly outside the waveguide cavity, with a sensor spacing of 1.5 millimeters, and the arrangement direction is consistent with the extension direction of the adsorbed mark. Through analysis of the thermal response curve, after 60 seconds of continuous excitation, it can be measured that the temperature rise area gradually extends from the original adsorption position to the end sensor, with a maximum temperature difference of 2.9 degrees Celsius, indicating that the energy has been effectively dragged to a position away from the original standing wave center of the cavity. At the same time, in order to avoid path interruption, low-power stable-amplitude pulses with phase matching are continuously injected at the end of the flow path, with a frequency of 24.65 GHz and a power of -14 dBm, so that the energy maintains a forward trend without reversing and standing in the middle of the path. The entire flow path exhibits good energy stable migration ability in continuous operation, laying a solid foundation for subsequent setting of energy release structures based on this path.

[0071] S4, sequentially opening the controllable coupling micro-holes along the energy drainage trajectory to form a ring-shaped bypass channel to stably transfer the energy being dragged along the channel to the heat dissipation boundary region;

[0072] After successfully guiding the energy along the adsorption mark direction to form a continuous drainage path by phase reversal micro-pulse, it is necessary to build a conductive structure with controllable discharge characteristics on the basis of the energy drainage path to stably output the energy being dragged from the resident path to the heat dissipation region at the chip boundary while avoiding the resident superposition phenomenon in the path. The specific implementation is as follows:

[0073] Combined with the formed energy drainage trajectory, three-dimensional space scanning modeling is performed along the main axis direction of the path, and the actual distribution data of the drainage trajectory on the inner wall of the cavity is collected with an accuracy control within 10 microns. According to the modeling results, equidistant hole points are selected on the trajectory, and the hole spacing is set according to the energy density distribution. The higher the energy density, the denser the holes in the area, and the average spacing is controlled between 1.2 mm and 2.4 mm. To avoid the influence of the hole structure on the overall structural integrity of the waveguide, the hole diameter is strictly controlled between 0.15 mm and 0.25 mm, the hole depth is consistent with the cavity wall thickness but does not penetrate the cavity, and only opens to the critical boundary. The hole shape adopts a truncated cone design with a wide entrance and a narrow bottom. The inner wall is treated by plasma polishing with a surface roughness controlled at the nanometer level, thereby forming a stable coupling channel. All hole sites are processed on a precision laser engraving platform with a processing accuracy of ±5 microns or less, and are verified one by one by a non-contact interferometer.

[0074] To ensure that the holes can actively respond and timely discharge energy during the energy drainage process, a micro-motion piece structure with temperature-sensitive swelling ceramic as the core material is embedded in each micro-hole. The structure is made of two layers of swelling response materials interlaced and compounded, and has the physical response characteristics of rapidly opening above 35 degrees Celsius and rapidly closing after temperature drop. The activation threshold of the temperature-sensitive structure is designed according to the temperature rise curve in the previous stage of energy drainage process to ensure that the micro-hole will automatically open only when the local energy in the drainage path reaches the set value, thereby having the ability of regional perception and response. Through this structure arrangement, energy will gradually couple with the holes in the trajectory path. When the local energy density in the path increases, the corresponding micro-hole automatically opens to realize the active diversion of energy from the main path to the lateral channel, effectively avoiding the re-concentration of energy in the main drainage path.

[0075] In order to orderly collect and guide the energy leaked from the main path to the heat dissipation boundary after the micro hole is opened, a parallel energy bypass channel is arranged around the outside of the waveguide. The channel is made of high thermal conductivity ceramic structure, filled with honeycomb silicon carbide layer with electromagnetic absorption ability, the thickness is not more than 3mm, the channel width is consistent with the total distribution band of the micro hole, and the channel is opened in a shallow groove close to the outer wall of the waveguide when laid, the groove depth is not more than 2mm, which is used to accommodate the channel material. When the energy is leaked through the micro hole, it directly enters the inner wall of the channel, and is guided to the energy release area at the tail end of the channel after multiple absorption and reflection in the silicon carbide structure. The entrance of the channel is provided with a buffer section to avoid local heat accumulation caused by sudden energy injection, and the length of the buffer section is controlled to be 12% of the total length of the channel. The whole bypass channel is in a ring structure, which is laid around the waveguide cavity for one turn, and finally converges to the heat dissipation lead-out section of the chip shell boundary, ensuring that the drainage energy has a complete path during the transfer process.

[0076] A set of heat dissipation absorption layers based on phase change heat conduction materials are arranged at the end structure of the bypass channel, which is a germanium-gallium-based composite material with the ability to rapidly melt and release latent heat when the temperature reaches 45 degrees Celsius. After the energy is transmitted to this place, the residual high-frequency energy will be converted into heat energy and absorbed by the absorption layer in time, thereby ensuring the continuity and stability of the whole energy drainage-out-heat dissipation process. In order to maintain the dynamic response ability of the bypass channel, multiple point heat conduction graphite sheets are uniformly embedded in the channel wall surface to improve the heat conduction efficiency and prevent edge temperature rise. The overall structure of the channel shows good thermal stability and energy release capacity in multiple operation cycles. Through this structure, a seamless connection from the energy traction trajectory to the energy transfer path is realized, so that the whole process of energy from the resident source point to the controllable release area through active traction, automatic diversion and smooth transfer forms a closed conduction link, ensuring that energy will not be aggregated or reflected in any node.

[0077] S5, a breathing boundary migration mechanism is established through the ring-shaped bypass channel, and the position and posture of the periodically micro-moved waveguide cavity wall are changed to make the energy distribution change continuously, disperse the standing wave focal point, and enhance the dynamic regulation and stable release ability of high-frequency energy;

[0078] After the high-frequency energy successfully leaks out through the controllable coupling micro hole and continuously transfers to the heat dissipation boundary area along the ring-shaped bypass channel, in order to prevent the formation of a new standing wave aggregation area at the end area and improve the overall release efficiency of energy in the structure range, controllable dynamic disturbance needs to be introduced to the waveguide cavity itself. The specific implementation is as follows:

[0079] The bottom support structure of the annular side channel path arranged on the periphery of the waveguide structure is finely cut and designed with adjustable connection. The cavity boundary constructed mainly of ceramic composite material is divided into multiple segmented units with micro-displacement capability, with each unit length controlled within 12 millimeters, and connected to each other through high-strength nickel-titanium memory alloy connectors. These connectors have temperature-induced expansion properties and can produce a stretching and contracting change of no more than 40 microns in length direction after receiving an excitation signal. The stretching and contracting rate is controlled at one time per second, and the response period is set synchronously with the aforementioned micro-hole opening frequency to ensure that the structure disturbance and energy leakage rhythm are consistent. By activating these connectors, the overall shape of the waveguide cavity can be periodically changed in space, including radial expansion and contraction and axial torsion, so that the energy field boundary conditions are disturbed in time sequence, thereby weakening the stability of the standing wave field at a fixed position.

[0080] To further enhance the directionality and controllability of structural disturbance, multiple groups of embedded ceramic hinges are arranged on the upper surface of the waveguide cavity. These hinges are sintered from polycrystalline zirconia, with a thickness of about 0.8 millimeters and arranged in an arc on the top surface of the waveguide. Each group of three hinges forms a deflectable unit, with a deflection angle of ±2 degrees in the excited state. In cooperation with the periodic stretching and contraction of the bottom memory alloy connectors, these hinge structures can form slight fluctuations on the surface of the cavity, causing the overall structure to have a slight "drumming" state in time sequence, simulating a boundary expansion and contraction movement similar to breathing. This non-rigid structural response mode does not damage the original waveguide structure's conduction characteristics, but can introduce disturbance perturbations at the energy conduction boundary, thereby continuously disturbing the formation of energy residence sites and enhancing the energy transfer flow trend. High-frequency response tests show that under the above structure excitation, the spatial drift range of the energy hot spot area reaches 6.4 millimeters, with a drift period of 24 times per minute, significantly dispersing the original standing wave focus center.

[0081] To improve the direction consistency of the energy disturbance process, a controllable phase adjustment medium sheet is uniformly embedded below the annular side channel of the outer wall of the structure. The medium sheet is formed by laminating high molecular composite ferrite and flexible polyester, with a thickness of about 0.25 mm, a sheet structure length of about 20 mm, and a width consistent with the channel. During the structure disturbance action, the dielectric constant of the medium sheet will be fine-tuned due to the deformation direction, with a change amplitude of not more than 2%. This small amplitude change in dielectric constant is sufficient to affect the propagation speed and path curvature of the energy in the channel, causing the energy originally transmitted along the fixed path to appear slight deflection and trajectory wandering during the disturbance process. After being affected by the periodic medium disturbance and boundary deformation during the propagation process, the standing wave focusing phenomenon is completely broken, and the energy distribution shows a trend of multi-point expansion and multi-zone release. This mechanism also has high stability under long-term continuous operation. After 180 minutes of operation test, no re-formation of any fixed energy hot spot is observed, and the energy output power fluctuation range is controlled within ±0.4 dBm.

[0082] To control the overall frequency, rhythm and stability of the structure disturbance, an active guide assembly is provided at both ends of the waveguide structure. The assembly includes a double-axis displacement controller and an optical fiber trigger control end. The displacement controller adopts a piezoelectric ceramic driving mode, which can accurately adjust the displacement fluctuation of the waveguide end structure within microns, thereby affecting the response period and boundary behavior of the overall structure. Through the optical fiber trigger mode, the external sensing signals such as the aforementioned micro-hole release state and hot spot displacement state are fed back to the displacement controller, realizing closed-loop adjustment of the disturbance frequency. For example, when it is detected that the standing wave hot spot formation time exceeds a preset threshold (such as 3 seconds), the controller will automatically increase the disturbance frequency to 1.5 times per second, shorten the standing wave formation period and trigger energy release in advance. Through this feedback control mode, the structure disturbance and energy state form a cooperative response relationship, further improving the active control ability of the high-frequency energy release process. The structure exhibits excellent stability and response speed during operation in the typical frequency band, and can break the standing wave formation condition in a very short time, providing a stable and controllable release channel for the entire energy control process.

[0083] The present application takes the accurate identification of the standing wave path as the starting point, combines high-frequency energy selective adsorption, phase reverse micro-disturbance guidance, controllable coupling release and dynamic boundary disturbance, and constructs a closed energy regulation path running through "identification-marking-dragging-forwarding-release". Especially by introducing the periodic micro-disturbance mechanism, the energy aggregation focus originally formed stably is continuously dispersed in time and space, the occurrence of energy standing condition is inhibited from the root, the uniform release of high-frequency energy and the dispersion output of heat are realized, the structural stability and thermal reliability of the chip under high-frequency, multi-mode and long-time working conditions are effectively improved, and the service life of the chip is prolonged.

[0084] The application provides a method for processing radio frequency signals of a radio frequency transceiver chip Figure 1 With Figure 2 The processing system of the radio frequency signals of the radio frequency transceiver chip is shown in the drawings, and comprises a standing wave positioning module, an energy marking module, a phase guiding module, a channel transfer module and a boundary control module.

[0085] The standing wave positioning module performs a slow frequency sweep operation inside the waveguide and applies a thermal disturbance, guides the energy distribution by frequency change to form a bright-dark fluctuation trajectory, extracts a standing wave shadow line from the continuous bright-dark rhythm to locate the energy gathering area.

[0086] The energy marking module adheres a tearable micro-absorption layer on the waveguide cavity wall corresponding to the standing wave shadow line, uses the selective adsorption effect of the micro-absorption layer surface on high-frequency energy to form a stable adsorption mark at the energy retention position to establish a drainage anchor point.

[0087] The phase guiding module injects a phase-reversed micro-pulse into the adsorption mark position, causes the cavity energy to be phase-tracked in the direction of the adsorption mark and gradually move outward, thereby constructing a continuous energy guiding track.

[0088] The channel transfer module sequentially opens controllable coupling micro-holes along the energy guiding track to form a ring-shaped bypass channel to stably transfer the tracked energy along the channel to the heat dissipation boundary area.

[0089] The boundary control module establishes a breathing boundary migration mechanism through the ring-shaped bypass channel, changes the position and posture of the waveguide cavity wall by periodic micro-movement, causes the energy distribution to change continuously, scatters the standing wave focal point, and enhances the dynamic control and stable release ability of the high-frequency energy.

Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the application.
