[0017] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] In related technologies, data transmission between PCB board connectors relies on wired connections, such as using cables or optical fibers to directly connect the male and female connectors (i.e., the transmitter and receiver). This connection method suffers from low heat dissipation efficiency in high-density, highly complex electronic systems such as servers and communication equipment because the cables occupy a large amount of space and obstruct airflow.

[0019] To address the aforementioned issues, this application provides a connector designed to solve the problem of low heat dissipation efficiency in high-density electronic devices caused by wired connections, where cables occupy significant space and obstruct airflow. The connector integrates a transmitting module and transmitting antenna at its transmitting end, and a receiving module and receiving antenna at its receiving end. The transmitting module converts the raw electrical signal into an electromagnetic wave signal, and the receiving module converts the electromagnetic wave signal back into a raw electrical signal to enable wireless data transmission. This significantly reduces the use of traditional cables, optimizing the internal layout and space utilization of the device. Furthermore, reducing the use of traditional cables helps minimize the space occupied by cables within the chassis, thereby optimizing airflow layout, improving heat dissipation efficiency, and lowering the device's operating temperature. Simultaneously, compared to fiber optic connections, which are prone to breakage and have higher maintenance costs, wireless radio frequency transmission is lower in cost and easier to maintain.

[0020] This application provides a connector structure, such as... Figure 1 As shown, Figure 1This is a structural diagram of an optional connector provided in an embodiment of this application; wherein, the connector includes a transmitting end and a receiving end, the transmitting end includes a transmitting antenna, a transmitting module and a plurality of first pins, and the two ends of the transmitting module are respectively connected to the transmitting antenna and the plurality of first pins; the receiving end includes a receiving antenna, a receiving module and a plurality of second pins, and the two ends of the receiving module are respectively connected to the receiving antenna and the plurality of second pins; wherein,

[0021] The transmitting module is used to receive raw electrical signals through multiple first pins, convert the raw electrical signals into electromagnetic wave signals, and transmit the electromagnetic wave signals to the receiving antenna through the transmitting antenna;

[0022] The receiving module is used to receive electromagnetic wave signals through a receiving antenna, convert the electromagnetic wave signals into raw electrical signals, and send the raw electrical signals to multiple second pins.

[0023] It should be noted that the transmitting end (male) of the connector may include a transmitting antenna, a transmitting module, and multiple first pins connected to the transmitting module. One end of the transmitting module is connected to the transmitting antenna, and the other end is connected to the multiple first pins. The receiving end (female) of the connector may include a receiving antenna, a receiving module, and multiple second pins. One end of the receiving module is connected to the receiving antenna, and the other end can be connected to the multiple second pins.

[0024] The transmitting end can be part of the connector. In the transmitting end, the transmitting module can be used to obtain the original electrical signal from multiple first pins, convert the original electrical signal into an electromagnetic wave signal, and transmit it through the transmitting antenna. The receiving end can be another part of the connector. In the receiving end, the receiving module can receive the electromagnetic wave signal from the receiving antenna, convert the electromagnetic wave signal into an original electrical signal, and send the original electrical signal to multiple second pins.

[0025] Optionally, such as Figure 2 As shown, both the transmitting and receiving modules can be modules equipped with radio frequency (RF) functionality. RF refers to electromagnetic frequencies that can radiate into space, typically ranging from 200kHz to 300GHz; it is a general term for high-frequency alternating electromagnetic waves. Optionally, the transmitting and receiving modules transmit data via specific RF frequencies, effectively avoiding interference with other wireless signals. These specific RF frequencies are selected from one or more of the 2.4GHz, 5GHz, and 60GHz frequency bands.

[0026] An antenna can be a component used to transmit or receive electromagnetic waves. A transmitting antenna can be a component that radiates electromagnetic wave signals generated by a transmitting module into space, used to transmit wireless signals. A receiving antenna can be a component that captures electromagnetic wave signals in space, used to receive signals transmitted by the transmitting antenna.

[0027] Optionally, such as Figure 2 As shown, both the transmitting and receiving antennas can be built-in antennas. The frequency bands of the transmitting and receiving antennas can be set by utilizing the directionality and shielding functions of the built-in antennas, thereby improving the signal purity and security of wireless data transmission and reducing the risk of data being illegally intercepted.

[0028] A transmitting module can integrate a device that converts electrical signals into electromagnetic wave signals. Similarly, a receiving module can integrate a device that converts electromagnetic wave signals captured by a receiving antenna into electrical signals.

[0029] Optionally, the electromagnetic wave signal can be a high-frequency electromagnetic wave signal, i.e., a high-frequency electromagnetic wave signal. High-frequency electromagnetic wave signals refer to electromagnetic wave signals with frequencies in the radio frequency (RF) range, which is generally defined between 300 kHz and 300 GHz. Generally, high-frequency electromagnetic wave signals have characteristics such as short wavelength, long transmission distance, and large bandwidth.

[0030] Optionally, the number of the first pin and the number of the second pin can be the same. Both the first and second pins can be PINs. In electronic devices and circuit boards, a PIN refers to a metal contact point used for connecting and transmitting signals, power, etc., and is often found on components such as connectors and chip packages. (Reference) Figure 3 , Figure 3 This is a schematic diagram of another optional connector provided in this application embodiment. Taking a server chassis as an example, in the server chassis, two PCBs (i.e., board A and board B) need to communicate with each other. A transmitting module is designed on the connector of board A, and a receiving module is designed on the connector of board B, transmitting high-frequency electromagnetic wave signals through an antenna. The transmitting module converts the electrical signal received from the first pin to obtain a high-frequency electromagnetic wave signal, and sends the high-frequency electromagnetic wave signal to the receiving antenna of the connector of board B through the antenna. The receiving module first captures the electromagnetic wave signal through the antenna, recovers the original electrical signal from the high-frequency electromagnetic wave signal, and outputs it to the circuit of board B through the second pin. To ensure efficient signal transmission and reception, the antennas of the transmitting and receiving ends can be designed with matching frequencies and modes. Furthermore, the transmitting and receiving modules are sealed to reduce environmental interference and improve signal stability and reliability. In practice, the transmitting end is generally placed on the motherboard, and the receiving end is placed on the daughterboard.

[0031] Specifically, the first pin can be the interface of the connector's transmitting end, used to receive raw electrical signals from the motherboard or other boards and transmit them wirelessly to the transmitting module. The second pin can be the interface of the connector's receiving end, used to receive the electrical signals demodulated and decoded by the receiving module and output them to the circuitry of the receiving board. There is a corresponding relationship between the first and second pins, determined by the connector design and signal transmission requirements, ensuring accurate data transmission from the transmitting end to the receiving end. The connector typically has markings or numbers indicating the function and corresponding electrical characteristics of each pin.

[0032] The connector provided in this application includes a transmitting end and a receiving end. The transmitting end includes a transmitting antenna, a transmitting module, and multiple first pins. The receiving end includes a receiving antenna, a receiving module, and multiple second pins. The two ends of the receiving module are connected to the receiving antenna and the multiple second pins, respectively. The transmitting module and transmitting antenna are integrated at the transmitting end of the connector, and the receiving module and receiving antenna are integrated at the receiving end. The transmitting module converts the raw electrical signal into an electromagnetic wave signal, and the receiving module converts the electromagnetic wave signal back into a raw electrical signal to achieve wireless data transmission. This significantly reduces the use of traditional cables and optimizes the internal layout and space utilization of the device. Furthermore, by reducing the use of traditional cables, the internal space occupied by cables is reduced, thereby optimizing the airflow layout, improving the system's heat dissipation efficiency, and lowering the device's operating temperature. This solves the problem in related technologies where cables occupy a large amount of space, obstructing airflow and resulting in low heat dissipation efficiency. Simultaneously, wireless connectivity reduces the maintenance complexity associated with cables.

[0033] In an exemplary embodiment, to improve the security of wireless data transmission and prevent data from being illegally intercepted and cracked during transmission, the data can be encrypted before being sent. Specifically, the transmitting module includes an encoder and a first signal conversion unit. The encoder's two ends are respectively connected to a plurality of first pins and the first signal conversion unit, wherein...

[0034] The encoder is used to receive the original electrical signal through multiple first pins, perform encoding preprocessing on the original electrical signal to obtain the preprocessed original electrical signal, and send the preprocessed original electrical signal to the first signal conversion unit. The encoding preprocessing includes encoding processing and encryption processing.

[0035] The first signal conversion unit is used to convert the preprocessed original electrical signal into an electromagnetic wave signal and send the electromagnetic wave signal to the receiving antenna through the transmitting antenna.

[0036] It should be noted that the transmitting module may include an encoder and a first signal conversion unit. One end of the encoder is connected to multiple first pins, the other end of the encoder is connected to one end of the first signal conversion unit, and the other end of the first signal conversion unit is connected to the transmitting antenna.

[0037] The transmitting module can be used to convert raw electrical signals into electromagnetic wave signals, and can include functions such as signal preprocessing, signal conversion and signal transmission.

[0038] The first pin can refer to the signal input pin on the connector's transmitting end. This first pin is responsible for receiving raw electrical signals from the PCB board and directing them to the encoder for processing. These raw electrical signals may originate from various data sources, such as processors, memory, or other I / O devices.

[0039] An encoder can be a device in a transmitting module used to process raw electrical signals. Encoders can encode and encrypt raw electrical signals to improve transmission efficiency and security. Encoding preprocessing can include encoding and encryption, ensuring that the signal is not easily interfered with or eavesdropped on during transmission. Encoding may involve data compression and the addition of error detection codes, while encryption uses specific encryption algorithms to convert the data into ciphertext.

[0040] The first signal conversion unit can refer to a component that converts the pre-processed original electrical signal into an electromagnetic wave signal. The electromagnetic wave signal obtained after conversion by the first signal conversion unit can be transmitted to the receiving end through the transmitting antenna of the transmitting end. The electromagnetic wave signal, transmitted through the transmitting antenna, is an electromagnetic wave with a specific frequency and intensity. In wireless communication, the electrical signal is encoded and converted into an electromagnetic wave signal, which then propagates through the air to the receiving end.

[0041] The receiving antenna can be used to capture electromagnetic wave signals transmitted by the transmitting antenna. Once the signal is captured, the receiving antenna will guide the received electromagnetic wave signal to the receiving module for signal processing.

[0042] This embodiment achieves wireless data transmission between PCB boards through a transmitting module, a receiving module, a transmitting antenna, and a receiving antenna. This eliminates the physical limitations of traditional cables, allowing for more flexible component layout on the PCB board, unaffected by cable paths and lengths. Reduced cable usage lowers maintenance costs due to cable wear and failure, while improving system reliability. The removal of cables frees up internal space, promoting airflow and improving overall system heat dissipation. Encoding and encryption using an encoder enhances the security of wireless signals, reducing the risk of eavesdropping or malicious interference.

[0043] In an exemplary embodiment, the first signal conversion unit includes an oscillator, a modulator, a power amplifier, and a frequency converter connected in series, with the frequency converter connected to a transmitting antenna;

[0044] The oscillator is used to receive the pre-processed raw electrical signal, convert the pre-processed raw electrical signal into a radio frequency signal, and send the radio frequency signal to the modulator;

[0045] A modulator is used to receive radio frequency signals, modulate the radio frequency signals to obtain modulated radio frequency signals, and send the modulated radio frequency signals to a power amplifier.

[0046] A power amplifier is used to receive modulated radio frequency signals, convert them into amplified radio frequency signals, and send the amplified radio frequency signals to a frequency converter.

[0047] A frequency converter is used to receive amplified radio frequency signals, convert them into electromagnetic wave signals, and then transmit the electromagnetic wave signals to a receiving antenna via a transmitting antenna.

[0048] It should be noted that the first signal conversion unit is the core component of the transmitting module, such as... Figure 4 As shown, the first signal conversion unit includes an oscillator, a modulator, a power amplifier, and a frequency converter. One end of the oscillator is connected to an encoder, the other end of the oscillator is connected to one end of the modulator, the other end of the modulator is connected to one end of the power amplifier, the other end of the power amplifier is connected to one end of the frequency converter, and the other end of the frequency converter is connected to a transmitting antenna.

[0049] In the first signal conversion unit, the preprocessed electrical signal is sequentially converted into a radio frequency (RF) signal, a modulated RF signal, and a power-amplified RF signal, ultimately converting it into an electromagnetic wave signal for transmission into space via a transmitting antenna. Specifically, an oscillator can be used to generate a stable RF signal. The oscillator receives the preprocessed raw electrical signal from the encoder and converts it into an RF signal of a specific frequency, which serves as the carrier wave for subsequent modulation. The modulator receives the RF signal generated by the oscillator and modulates the encoded electrical signal information onto the RF carrier wave to form a modulated RF signal. The power amplifier receives the modulated RF signal output from the modulator and amplifies its power to ensure effective air penetration and reach the receiving antenna. In wireless communication, signal power directly affects transmission distance and signal quality. The frequency converter receives the power-amplified RF signal from the power amplifier and converts it into an electromagnetic wave signal for transmission via the antenna. The frequency converter can convert the RF signal into a higher-frequency electromagnetic wave suitable for air transmission, or it can directly convert the RF signal into an electromagnetic wave form.

[0050] The frequency of a specific radio frequency signal can be adjusted according to different wireless communication standards and protocols to adapt to different frequency bands and channel conditions.

[0051] Specifically, in this embodiment, the encoder can also be placed before the power amplifier to achieve both encoding and encryption functions.

[0052] Optionally, the specific process of the modulator modulating the radio frequency signal may include: modulating the radio frequency signal with the original electrical signal according to a specified modulation strategy to obtain the modulated radio frequency signal, wherein the specified modulation strategy is one of the following modulation strategies: amplitude modulation strategy, frequency modulation strategy, phase modulation strategy, orthogonal amplitude modulation, orthogonal frequency division multiplexing, etc.

[0053] In this embodiment, an oscillator provides a stable radio frequency carrier, ensuring the accuracy and reliability of signal transmission. A modulator loads an electrical signal onto the radio frequency carrier, increasing the information carrying capacity of the wireless signal and improving data transmission rate and quality. A power amplifier enhances the signal power, significantly improving the transmission distance and penetration capability of the wireless signal, ensuring effective reception within the expected range. A frequency converter transforms the radio frequency signal into an electromagnetic wave signal suitable for air transmission, improving air transmission efficiency and reducing signal loss during transmission.

[0054] In one exemplary embodiment, the encoder includes a block coding unit and an encryption unit;

[0055] The group coding unit is used to perform grouping and sorting processing on the original electrical signal to obtain the coding information corresponding to the original electrical signal. Based on the coding information, the original electrical signal is encoded to obtain the encoded original electrical signal.

[0056] The encryption unit is used to perform specified encryption processing on the encoded original electrical signal to obtain the preprocessed original electrical signal.

[0057] It should be noted that encoders can be used to encode and encrypt raw electrical signals to improve the efficiency and security of wireless transmission. An encoder consists of a block coding unit and an encryption unit. The main function of the block coding unit is to perform block coding and sequencing processing on the raw electrical signal, dividing the continuous electrical signal into multiple data packets, each containing a certain amount of information. Block coding improves the flexibility of data transmission and error detection capabilities, while sequencing ensures that data packets are transmitted and received in the correct order. The encryption unit in the encoder is responsible for encrypting the encoded electrical signal using a specific encryption algorithm to protect the data security during transmission and prevent unauthorized access or data leakage. Specifically, the specific encryption algorithm can be a symmetric encryption algorithm or an asymmetric encryption algorithm.

[0058] Optionally, the block coding unit can group and sort the original electrical signal according to the sequence number of each of the multiple first pins to obtain the coding information corresponding to the original electrical signal. Based on the coding information, the original electrical signal is encoded to obtain the encoded original electrical signal. The encoding process may also include the generation of error detection codes, such as cyclic redundancy check or forward error correction codes, for detecting and correcting transmission errors at the receiving end.

[0059] The encryption unit uses a specific encryption algorithm to encrypt the encoded data packet, generating ciphertext. In practice, the selection of the encryption algorithm needs to comprehensively consider encryption strength, encryption speed, and computational resource consumption. The encryption unit may also include key management functions to ensure the security of the encryption and decryption processes.

[0060] In this embodiment, the combined use of the encryption unit and the block coding unit in the encoder not only enhances data security but also improves the reliability of data transmission, ensuring data integrity and accuracy even in harsh wireless communication environments.

[0061] In an exemplary embodiment, in order to ensure high quality and high efficiency of signal transmission, a gain table can be provided in the power amplifier. The gain table includes multiple gains corresponding to multiple signal strengths, and one gain corresponds to one of the multiple signal strengths.

[0062] The power amplifier is also used to look up the gain table based on the signal strength of the modulated RF signal to obtain the target gain, and then amplify the modulated RF signal according to the target gain to obtain the power-amplified RF signal.

[0063] It should be noted that a power amplifier can be used to amplify the power of a modulated radio frequency signal to a level sufficient for effective transmission through an antenna. Specifically, the power amplifier incorporates a gain table, which includes multiple gains corresponding to various signal strengths. The existence of the gain table allows the power amplifier to select the optimal amplification gain based on the current signal strength. The gain table can be established based on experimental data to ensure that the amplified signal meets the quality requirements of wireless communication under different signal strengths.

[0064] Specifically, the power amplifier can have a built-in signal detection circuit to monitor the strength of the received radio frequency signal in real time. Based on the detected signal strength, it can look up the gain table to find the gain value that best matches the current signal strength. Based on the target gain found in the gain table, it can automatically adjust the gain of the amplifier circuit to ensure that the power of the amplified signal is appropriate, so that there is no signal attenuation due to insufficient power, nor nonlinear distortion or interference due to excessive power.

[0065] To prevent damage to the power amplifier due to excessively high signal strength, the power amplifier may also include overload protection. The power amplifier may also employ linear or nonlinear amplification techniques to meet specific signal processing requirements.

[0066] In this embodiment, a gain meter is provided in the power amplifier. Through the dynamic gain control of the gain meter, intelligent power adjustment of the modulated radio frequency signal is realized, which to a certain extent ensures the quality of the signal during transmission and reduces data transmission errors caused by insufficient signal strength.

[0067] In one exemplary embodiment, the receiving module includes a second signal conversion unit and a decoder, wherein the two ends of the second signal conversion unit are respectively connected to a receiving antenna and a decoder, wherein...

[0068] The second signal conversion unit is used to receive electromagnetic wave signals through a receiving antenna, convert the electromagnetic wave signals into signals to be decoded, and send the signals to be decoded to the decoder.

[0069] The decoder is used to receive the signal to be decoded, perform decoding preprocessing on the signal to be decoded to obtain the original electrical signal, and send the original electrical signal to multiple second pins. The decoding preprocessing includes decryption processing and decoding processing.

[0070] It should be noted that the receiving module is the component in the connector used to receive electromagnetic wave signals and convert them into electrical signals. The receiving module can consist of a second signal conversion unit and a decoder. The function of the second signal conversion unit is to receive the electromagnetic wave signals captured by the receiving antenna and convert them into a processable signal to be decoded for subsequent decoding. The decoder receives the signal to be decoded output from the second signal conversion unit, performs decoding preprocessing, and ultimately recovers the original electrical signal. This decoding preprocessing includes decryption and decoding processes to ensure security and data integrity.

[0071] Optionally, the second signal conversion unit captures electromagnetic wave signals through a receiving antenna, performs signal conversion processing on the electromagnetic wave signals, and obtains the signal to be decoded. The signal conversion processing of the second signal conversion unit may include signal reception, spectrum conversion, etc.

[0072] This embodiment, employing a second signal conversion unit and a decoder, achieves efficient and secure data recovery. The decoder's decryption process ensures the security of the wireless communication system; only the receiver with the correct key can decrypt and use the data, thus improving the wireless communication's resistance to eavesdropping and hacking.

[0073] In one exemplary embodiment, the second signal conversion unit includes a filter, a high-frequency amplifier, a mixer, and a demodulator connected in series, wherein the filter is connected to a receiving antenna.

[0074] A filter is used to filter electromagnetic wave signals to obtain a target signal, and then send the target signal to a high-frequency amplifier. The target signal is the filtered electromagnetic wave signal.

[0075] A high-frequency amplifier is used to receive the target signal, amplify the target signal to obtain the amplified target signal, and send the amplified target signal to the mixer.

[0076] A mixer is used to receive the amplified target signal, perform frequency mixing on the amplified target signal to obtain an intermediate signal, and send the intermediate signal to a demodulator. The intermediate signal is the target signal after frequency mixing and amplification.

[0077] A demodulator is used to receive intermediate signals, demodulate them, and obtain the signal to be decoded.

[0078] It should be noted that the second signal conversion unit may include a filter, a high-frequency amplifier, a mixer, and a demodulator. For example... Figure 5 As shown, Figure 5This is a schematic diagram of an optional second signal conversion unit provided in an embodiment of this application. One end of the filter is connected to the receiving antenna, the other end of the filter is connected to one end of a high-frequency amplifier, the other end of the high-frequency amplifier is connected to one end of a mixer, the other end of the mixer is connected to one end of a demodulator, and the other end of the demodulator is connected to multiple second pins.

[0079] The second signal conversion unit converts the electromagnetic wave signal captured by the receiving antenna into a signal to be decoded for further data recovery and processing. Specifically, a filter is used to select signals within a specific frequency range from complex electromagnetic wave signals, removing noise and interference to ensure signal purity. The high-frequency amplifier enhances the signal strength of the target signal output by the filter to compensate for attenuation that may occur during wireless transmission, ensuring signal quality in subsequent processing. The mixer mixes the signal output from the high-frequency amplifier to obtain an intermediate frequency (IF) signal, facilitating demodulation by the demodulator. The demodulator then converts the IF signal generated by the mixer back to the original baseband signal, i.e., the signal to be decoded.

[0080] In this embodiment, the filter can be a bandpass filter to ensure that only the radio frequency signal captured by the receiving antenna is passed through, while other unwanted frequencies are suppressed. The high-frequency amplifier can include automatic gain control (AGC) to ensure stable amplification of the signal under different environmental conditions and avoid signal overload or under-amplification.

[0081] The demodulator is also used to demodulate the intermediate signal according to a specified demodulation strategy to obtain the demodulated electrical signal, i.e., the signal to be decoded. The specified demodulation strategy is one of the following demodulation strategies:

[0082] Amplitude demodulation, frequency demodulation, or phase demodulation.

[0083] In this embodiment, the second signal conversion unit achieves effective conversion and preprocessing from electromagnetic wave signals to electrical signals through the cascading use of a filter, a high-frequency amplifier, a mixer, and a demodulator. Specifically, the filter effectively removes noise and interference from the wireless channel, ensuring the purity of the signal in subsequent processing and reducing data transmission errors. The high-frequency amplifier enhances the signal strength, ensuring sufficient signal strength even after signal attenuation over long distances or in complex environments, meeting the signal requirements of the demodulator. The mixer enables the second signal conversion unit to adapt to signals of different frequencies, improving the versatility and flexibility of the receiving module.

[0084] In one exemplary embodiment, the decoder includes a decryption unit, a decoding unit, and an error correction unit;

[0085] The decryption unit is used to perform specified decryption processing on the signal to be decoded to obtain the decrypted electrical signal.

[0086] The decoding unit is used to decode the decrypted electrical signal to obtain the decoded electrical signal.

[0087] The error correction unit is used to perform error correction processing on the decoded electrical signal to obtain the original electrical signal.

[0088] It should be noted that a decoder may include a decryption unit, a decoding unit, and an error correction unit. In the decoder, the decryption unit performs specified decryption processing on the signal to be decoded, obtaining a decrypted electrical signal (i.e., an unencrypted electrical signal). The decoding unit converts the decrypted electrical signal back to its original form, i.e., data or control information. The error correction unit may be located in the final stage of the decoder, used to detect and correct errors that may occur during the decoding process, ensuring high reliability of data transmission.

[0089] Optionally, the decryption unit can use the same key and encryption algorithm as the encoder encryption unit to restore the data in the signal to its pre-encryption state. For example, the decryption process can employ symmetric or asymmetric encryption techniques. To ensure the accuracy of signal conversion and the correct ordering of data, the decoding unit can also include signal retiming and data reassembly functions. The error correction unit can detect any erroneous bits in the decoded signal and attempt to correct them. Optionally, techniques such as forward error correction can be used to detect and correct errors in the signal through additional redundant information, thereby improving the reliability of data transmission.

[0090] In this embodiment, the signal decryption by the decryption unit, the signal conversion by the decoding unit, and the error detection and correction by the error correction unit in the decoder not only ensure the security and accuracy of data transmission, but also improve the reliability of the wireless communication system.

[0091] In an exemplary embodiment, the mixer is further configured to select a target frequency signal from a plurality of preset frequency signals based on the frequency of the amplified target signal, and to perform a mixing process on the amplified target signal and the target frequency signal to obtain an intermediate signal, wherein the target frequency signal is the frequency signal with the smallest frequency difference from the amplified target signal.

[0092] It should be noted that the mixer can be used to convert the frequency of the received radio frequency signal into a fixed intermediate frequency for easier further processing. In this embodiment, the mixer is also responsible for selecting a local oscillator signal (i.e., the target frequency signal) that is closest to the frequency of the received signal for mixing. The target frequency signal can refer to the local oscillator signal used in the mixer to mix with the amplified target signal; the target frequency signal is the local oscillator signal with the closest frequency. Specifically, the target frequency signal is the frequency signal with the smallest frequency difference from the amplified target signal among multiple frequency signals.

[0093] The amplified target signal refers to the radio frequency signal whose signal strength is enhanced after being processed by a high-frequency amplifier.

[0094] Based on the application requirements of mixers, multipliers or phase detectors can be set in mixers to perform mixing operations to convert high-frequency signals into lower-frequency signals that are easier to process.

[0095] In this embodiment, the mixer selects a target frequency signal that is closest to the frequency of the received signal for mixing, converting the received signal into an intermediate frequency signal. The intermediate frequency signal has a lower frequency than the received radio frequency signal, which facilitates subsequent demodulation, decoding and other signal processing steps, thereby improving the efficiency and accuracy of signal processing.

[0096] In one exemplary embodiment, the mixer is provided with multiple oscillators for generating multiple frequency signals.

[0097] It should be noted that a mixer can contain multiple oscillators, each capable of independently generating a signal at a specific frequency. The frequency range of each oscillator covers the frequency range of the received radio frequency signal. The type of oscillator can be selected from phase-locked loop (PLL), direct digital frequency synthesis (DDS), or other frequency generation techniques to ensure signal stability and accuracy.

[0098] In one example, the mixer is connected to four oscillators, each generating signals covering four different frequency bands: 2.4 GHz, 5 GHz, 8 GHz, and 10 GHz, to accommodate various radio frequency (RF) communication standards. When RF signals of different frequencies are received, the frequency detection circuit in the mixer automatically identifies and instructs the mixer to select the appropriate oscillator signal for mixing. For example, if a 2.4 GHz signal is received, the mixer will select the oscillator signal corresponding to 2.4 GHz for frequency matching, ensuring the accuracy and efficiency of signal processing.

[0099] This embodiment integrates a multi-frequency oscillator and a mixer at the receiving end, significantly improving the connector's ability to receive and process radio frequency signals of different frequencies.
