[0030] This utility model proposes a 5G Red Cap module.

[0031] In the embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 As shown, the 5G Red Cap module includes an M.2 standard gold finger 1 and a 5G communication module 2. The gold finger 1 receives the power supply voltage from the 5G communication module 2. The gold finger 1 is used to connect with the 5G communication module 2 to obtain the PCIE signal transmitted by the transmitter of the 5G communication module 2. The gold finger 1 is connected to a first resistor R2, which is connected to the transmitter of the 5G communication module 2. The 5G communication module 2 is also connected to a second resistor R31 and a third resistor R32. The second resistor R31 and the third resistor R32 are respectively connected to the gold finger 1. The gold finger 1 transmits or receives USB data to the 5G communication module 2 through the second resistor R31 and the third resistor R32. The second resistor R31 and the third resistor R32 are respectively connected to a USB interface 3, which is used for data transmission.

[0032] This invention uses a gold finger 1 connected to a 5G communication module 2 to obtain the PCIE signal transmitted by the transmitter of the 5G communication module 2. The 5G communication module 2 transmits data through a second resistor R31 and a third resistor R32 connected to a USB interface 3. The M.2 compliant gold finger 1 and 5G communication module 2 achieve interface and signal compatibility. The first resistor R2, second resistor R31, and third resistor R32 limit the current flowing through the gold finger 1. By impeding the current flow, the first resistor R2, second resistor R31, and third resistor R32 prevent the current in the circuit from exceeding a predetermined value, thereby protecting other components in the circuit from damage due to excessive current.

[0033] The gold finger 1 is also connected to a filter circuit. One end of the filter circuit is connected to the spare power supply pin of the gold finger 1, and the other end of the filter circuit is grounded. The filter circuit includes a first capacitor C1, a second capacitor C2, and a third capacitor C3, which are connected in parallel. All three capacitors are electrolytic capacitors.

[0034] A filter circuit is used to remove unwanted frequency components from a signal. After rectification, the output direct current (DC) usually contains certain fluctuations or ripples. Filter circuits can remove these ripples, making the output voltage more stable. Filter circuits can also remove high-frequency noise, especially in power supply systems, to prevent high-frequency interference from entering other circuit parts and maintain system stability. Filter circuits can selectively allow signals of certain frequencies to pass while blocking unwanted frequency components, thus playing a role in eliminating unnecessary signals in signal processing.

[0035] Electrolytic capacitors have a large capacitance value, enabling them to store relatively more electrical energy. When the voltage changes, electrolytic capacitors can temporarily store energy, maintaining voltage stability in the filter circuit. In DC power supplies, they smooth the pulsating DC current after rectification. Electrolytic capacitors smooth the output voltage through the charging and discharging process, reducing ripple in the power supply. Electrolytic capacitors also have a decoupling effect, especially in digital circuits. They can stabilize the power supply voltage, prevent high-frequency noise and signal interference, and ensure the normal operation of the filter circuit.

[0036] The 5G communication module 2 is connected to an RF circuit, which is used to transmit radio frequency signals to the 5G communication module 2.

[0037] like Figure 4 As shown, RF circuits (radio frequency circuits) operate in the frequency range of several kilohertz (kHz) to several hundred gigahertz (GHz) and are commonly used in wireless communication, broadcasting, and other fields. RF circuits are primarily used to process and transmit high-frequency signals. Radio communication, Wi-Fi, Bluetooth, GPS, and mobile communication all require RF circuits to transmit and receive signals. In RF circuits, modulation transmits information by changing certain characteristics of the carrier signal (such as frequency, amplitude, or phase). The RF circuit is responsible for modulating the information signal to make it suitable for transmission over a wireless channel. The RF circuit is also responsible for demodulating the received modulated signal to recover the original signal content. The antenna ANT1 matching section in the RF circuit ensures that the RF signal can be transmitted or received efficiently.

[0038] The RF circuit includes a fourth capacitor C12, a fifth capacitor C13, a sixth capacitor C14, and a seventh capacitor C15. The fourth capacitor C12 and the fifth capacitor C13 are connected in series, and the sixth capacitor C14 and the seventh capacitor C15 are connected in parallel. One end of the fourth capacitor C12 is connected to the gold finger 1, and the other end of the fourth capacitor C12 is connected to one end of the fifth capacitor C13 and one end of the sixth capacitor C14, respectively. The other end of the fifth capacitor C13 is connected to one end of the seventh capacitor C15.

[0039] When the fourth capacitor C12 and the fifth capacitor C13 are connected in series, the total capacitance of the series capacitors will be smaller than the value of any single capacitor. If multiple capacitors are connected, the total capacitance will decrease. This is because the equivalent capacitance of a series capacitor is smaller than the capacitance of any single capacitor. Series capacitors can improve the voltage withstand capability of RF circuits and are used in circuits requiring high voltage withstand, especially in high-voltage filtering and power supply circuits. In series-connected capacitors, charge is distributed across each capacitor, so the voltage across each capacitor will be different, depending on its capacitance value.

[0040] The sixth capacitor, C14, and the seventh capacitor, C15, are connected in parallel. The total capacitance of the parallel capacitors is the sum of their individual capacitances. Therefore, increasing the number of parallel capacitors increases the total capacitance of the RF circuit. Because the total capacitance increases, the RF circuit can store more charge. This is especially useful in power supply circuits that require smooth current and stable voltage; a larger total capacitance can effectively store more electrical energy. Parallel capacitors can also reduce the total impedance in the RF circuit. Particularly in AC circuits, parallel capacitors can improve the transmission capability of AC signals and are commonly used for filtering and decoupling applications.

[0041] The RF circuit also includes an inductor WL1, which is connected in parallel with the sixth capacitor C14 and the seventh capacitor C15. Inductor WL1 is used for filtering, matching, and energy storage in the RF circuit. Inductor WL1 has impedance to high-frequency signals, effectively filtering out unwanted frequencies. It has lower impedance to low-frequency signals but higher impedance to high-frequency signals, thus filtering out high-frequency noise or unwanted signal components.

[0042] The RF circuit also includes a TVS diode D1, which is connected in parallel with the inductor WL1. The TVS diode D1 is primarily used to protect the circuit from transient high-voltage surges, such as lightning strikes, power surges, or electrostatic discharge (ESD). When a transient overvoltage reaches the RF circuit, the TVS diode D1 quickly conducts, diverting the excessive voltage or current to ground, thus protecting sensitive components in the circuit from damage. Its response time is extremely short, absorbing and dissipating high-voltage pulses within nanoseconds. In RF circuits, the TVS diode D1 is commonly used to protect input and output ports from ESD damage. Electrostatic discharge can originate from operators, the external environment, etc. The TVS diode D1 conducts during electrostatic discharge, rapidly releasing excess charge. The input and output ports in the RF circuit are typically connected to external devices or the antenna ANT1, making them susceptible to external transient voltage surges. The TVS diode D1 provides protection at these interfaces.

[0043] The RF circuit also includes an antenna ANT1. The gold finger 1 is provided with an antenna interface, and the antenna ANT1 is connected to the antenna interface for a diversity antenna ANT1 link. The output structure of the antenna ANT1 is an antenna clip. The antenna ANT1 is a key component in the RF circuit for signal transmission and reception. The function of the antenna ANT1 is to transmit electrical signals from the circuit to the air via electromagnetic waves, or to convert electromagnetic waves in the air into electrical signals for use by the circuit. In transmit mode, the antenna ANT1 converts electrical signals in the RF circuit into electromagnetic waves, which propagate through the air to a distance. In receive mode, the antenna ANT1 receives electromagnetic waves propagating from the air and converts them into electrical signals for processing by the circuit.

[0044] Based on the aforementioned antenna ANT1, the RF circuit also includes antenna ANT2, and antenna ANT2 is a main transceiver antenna ANT2 RF link.

[0045] It should be noted that the 5G communication module 2 described in this utility model is existing technology. The improvement of this utility model does not lie in the technology of this module itself. The 5G communication module 2 is a 5G Red Cap (reduced-capability, Red Cap), a lightweight 5G terminal that uses a chip of model MT5710-CN. Compared with traditional 5G terminals, the complexity of the 5G Red Cap terminal can be reduced by about 60% after being trimmed, which greatly reduces the complexity of the terminal. Secondly, the various capabilities and characteristics of 5G Red Cap ensure that it can be smoothly upgraded and introduced based on the existing 5G network. 5G Red Cap continues the various excellent characteristics of 5G NR, such as large bandwidth, low latency, high reliability, service guarantee, data not leaving the factory, low power consumption, strong coverage, and many other advantages, and can be introduced as needed for different application scenarios.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
