[0048] Specifically, the power bank module 110 refers to a portable power supply device designed to provide power to other electronic devices. The output interface is the connection interface on the power bank module 110, used to transfer power to other devices.

[0052] Figure 2 This is a schematic diagram of another radio frequency signal transmitting circuit provided in an embodiment of the present invention. Based on the above embodiments, the radio frequency energy module 120 can be further refined; optionally, such as... Figure 2 As shown, the radio frequency energy module 120 includes: a power supply module 121, a control module 122, a frequency synthesis module 123, a signal generation module 124, and a signal transmission module 125. The input terminal of the power supply module 121 is connected to the output interface of the power bank module 110, and the output terminal of the power supply module 121 is connected to the control module 122, the frequency synthesis module 123, the signal generation module 124, and the signal transmission module 125 respectively. The control module 122 is connected to the frequency synthesis module 123 and the signal transmission module 125 respectively, and the control module 122 is used to output control signals. The signal generation module 124 is connected to the frequency synthesis module 123 and is used to generate an initial radio frequency signal. The frequency synthesis module 123 is used to output a first radio frequency signal and a second radio frequency signal. The signal transmission module 125 is connected to the frequency synthesis module 123 and is used to transmit radio frequency signals externally.

[0053] Specifically, the power module 121 refers to a device that can convert the electrical energy provided by the power bank module 110 into voltage and current suitable for use in the internal circuitry of the radio frequency energy module 120, and can supply power to the radio frequency energy module 120.

[0054] The control module 122 refers to a module that can control the operation of other modules. It can receive input signals from the user or other modules and output control signals. For example, the control module 122 can be a microcontroller, a single-chip microcomputer, etc.

[0055] The frequency synthesis module 123 refers to a module used to generate radio frequency (RF) signals of a specific frequency. In this embodiment of the invention, the frequency synthesis module 123 uses the initial RF signal generated by the signal generation module 124, combined with internal digital circuitry, to generate a first RF signal and a second RF signal. Optionally, the first RF signal and the second RF signal are two differential RF signals. By using differential signals, the RF signal transmitting circuit can effectively reduce interference and noise during signal transmission, thereby improving the signal transmission quality.

[0056] The signal generation module 124 refers to a module capable of generating an initial radio frequency (RF) signal. This initial RF signal provides a basic signal input for the RF signal transmitting circuit. In this embodiment, the initial RF signal generated by the signal generation module 124 can be transmitted to the frequency synthesis module 123 to ensure that the frequency of the RF signal generated by the frequency synthesis module 123 is accurate and stable. For example, the signal generation module 124 can be a crystal oscillator, which generates an initial RF signal of a fixed frequency through oscillation.

[0057] The signal transmitting module 125 refers to the module that transmits the radio frequency signal generated by the radio frequency energy module 120 into the external environment. In this embodiment of the present invention, the signal transmitting module 125 can receive the first radio frequency signal and the second radio frequency signal generated by the frequency synthesis module 123, and then amplify and modulate these two radio frequency signals, and then transmit the processed radio frequency signal into the external environment to realize data transmission or communication functions.

[0058] In this embodiment of the invention, the power supply module 121 is responsible for supplying power to the radio frequency energy module 120. Under the control of the control module 122, the frequency synthesis module 123 uses the initial radio frequency signal emitted by the signal generation module 124 to generate a first radio frequency signal and a second radio frequency signal. The signal transmission module 125 amplifies and modulates these two radio frequency signals and then transmits them to the external environment.

[0059] This invention generates a first radio frequency (RF) signal and a second RF signal through a frequency synthesis module, and transmits the RF signal externally through a signal transmission module, providing a stable power source for passive IoT devices. The differential RF signaling method employed in this invention gives the RF signal transmitted by the signal transmission module excellent anti-interference capabilities, enabling stable operation in complex environments and ensuring the accuracy and reliability of data transmission.

[0060] Figure 3This is a schematic diagram of another radio frequency signal transmitting circuit provided in an embodiment of the present invention. Based on the above embodiments, the signal transmitting module 125 can be further refined, such as... Figure 3 As shown, optionally, the signal transmitting module 125 includes: a balun circuit 126, which combines the first radio frequency signal and the second radio frequency signal into a third radio frequency signal; a radio frequency switch 127, which is connected to the control module 122 and the balun circuit 126 respectively; a power amplifier circuit 128, which is connected to the radio frequency switch 127 and is used to amplify and enhance the third radio frequency signal; and an antenna 129, which is connected to the power amplifier circuit 128.

In this embodiment of the invention, the balun circuit 126 combines the differential first and second radio frequency signals into a single radio frequency signal, namely the third radio frequency signal. Figure 4 This is a schematic diagram of a balun circuit provided as an embodiment of the present invention. Figure 4 As shown, the first radio frequency signal RF+ and the second radio frequency signal RF- are input to the balun chip T1 through the first capacitor C6 and the second capacitor C16. After being processed by the balun chip T1, the third radio frequency signal RF1 is output.

[0062] The radio frequency switch 127 refers to a circuit component for controlling the path of radio frequency signals, capable of switching between different signal sources or outputs, and able to select the signal transmission path according to instructions from the control module 122. For example, Figure 5 This is a schematic diagram of the control signals received by the radio frequency switch according to an embodiment of the present invention. Figure 5 As shown, the control module 122 can emit continuous carrier signals and carrier signals with duty cycles to control the switching state of the RF switch 127. If the control module 122 emits a continuous carrier signal, the RF switch 127 is in the normally open state, and the RF energy module 120 can continuously emit RF signals, which is suitable for working applications requiring a large amount of RF energy for a short period of time. If the control module 122 emits a carrier signal with a duty cycle, the RF switch 127 alternates between closing and opening, and the RF energy module 120 emits intermittent RF signals with a certain duty cycle, which is suitable for applications requiring long-term operation and can save energy.

[0063] The power amplifier circuit 128 refers to a circuit that amplifies and enhances the third radio frequency signal. By enhancing the strength of the third radio frequency signal, the power amplifier circuit 128 ensures that the enhanced radio frequency signal can effectively penetrate obstacles and reach the receiving end, thereby improving communication quality. For example, the power amplifier circuit 128 can implement power amplification and enhancement using the SPA-2118 chip.

[0064] Antenna 129 refers to a component used for transmitting and receiving radio frequency signals. In this embodiment of the invention, antenna 129 is used to transmit the radio frequency signal output by power amplifier circuit 128 to the external environment.

[0065] In this embodiment of the invention, the balun circuit 126 combines the differential first and second radio frequency signals into a third radio frequency signal. This third radio frequency signal is amplified and enhanced by the power amplifier circuit 128, and then transmitted to the outside via the antenna 129. A radio frequency switch 127 is connected between the balun circuit 126 and the power amplifier circuit 128. By controlling the on / off frequency of the radio frequency switch 127, the state of the radio frequency signal transmitted by the radio frequency energy module 120 can be controlled to adapt to different working environments.

[0066] This invention transmits radio frequency (RF) signals to the external environment through a balun circuit, a power amplifier circuit, and an antenna. The RF signal state is controlled by an RF switch, enabling safe and stable RF signal output while ensuring the RF power module can be matched to different application scenarios. This invention improves the reliability and flexibility of the RF signal transmission circuit.

[0068] Specifically, the first button 130 refers to a switch used to control the operating state or mode of the radio frequency energy module 120. The first button 130 is connected to the control module 122. After pressing the first button 130, the control module 122 receives the input signal and switches the operating mode of the radio frequency energy module 120 according to preset logic or conditions. For example, a short press of the first button 130 puts the radio frequency energy module 120 into operating mode, enabling it to transmit radio frequency signals; a long press of the first button 130 puts the radio frequency energy module 120 into low-power standby mode, preventing it from transmitting radio frequency signals.

[0069] See also Figure 3Based on the above embodiments, optionally, the radio frequency energy module 120 further includes: a first indicator light 131, which is connected to the control module 122 and is used to indicate the working mode of the radio frequency energy module 120.

[0070] Specifically, the first indicator light 131 refers to a visual feedback device that, through connection with the control module 122, displays the real-time operating status of the radio frequency energy module 120. For example, when the radio frequency energy module 120 is in normal operating mode, the first indicator light 131 is constantly lit; when the radio frequency energy module 120 is in low-power standby mode, the first indicator light 131 flashes; when the radio frequency energy module 120 malfunctions or does not receive power from the power bank module 110, the first indicator light 131 is off.

[0071] This embodiment of the utility model controls the working mode of the radio frequency energy module through a first button and indicates it through a first indicator light, which helps to improve the convenience and intuitiveness of user operation.
