[0002] A wireless network adapter is a terminal wireless network device that enables a computer to connect to a wireless network, such as WiFi or Bluetooth.

[0003] The 2.4GHz WiFi and Bluetooth communication links share the 2.4GHz frequency band. In order to reduce costs and shrink the size of the wireless network card during design, the 2.4GHz WiFi and Bluetooth communication links usually share a single antenna through time-division multiplexing. Specifically, the 2.4GHz WiFi and Bluetooth communication links are connected to an RF switch, which is connected to the antenna. The main chip sends a switching signal through internal calculations to control the RF switch to switch the communication links.

[0004] However, this approach increases the computational load on the main chip, and the complex internal signals of the main chip can interfere with each other, which may lead to errors in the calculated switching signals, resulting in unstable signals and poor communication quality in the 2.4GHz WiFi and Bluetooth communication links.

[0028] Figure 1 This is a schematic diagram of the structure of a wireless network card provided by this utility model, as shown below. Figure 1 As shown, the wireless network card includes:

[0029] The main chip 110 includes a first 2.4GHz WiFi transceiver port and a Bluetooth transceiver port. The main chip 110 provides WiFi and Bluetooth functions. The first 2.4GHz WiFi transceiver port is used to transmit and receive 2.4GHz WiFi signals, and the Bluetooth transceiver port is used to transmit and receive Bluetooth signals. For example, in this embodiment of the invention, the Bluetooth signal operates in the 2.4GHz frequency band.

[0030] A first radio frequency (RF) switch 121 is connected to both a first 2.4GHz WiFi transceiver port and a first Bluetooth transceiver port. An RF switch is a key component used in wireless communication devices to control the on / off state and path switching of radio frequency signals. It can flexibly switch between multiple RF signal paths, ensuring stable and efficient information reception and transmission. RF switches are typically composed of high-frequency switching chips and external components, and are widely used in mobile phones, Wi-Fi, Bluetooth, GPS, and other systems. Their working principle is to select different signal paths by controlling signals to achieve flexible signal routing and efficient transmission. In this embodiment of the invention, the first RF switch 121 is used to select the 2.4GHz WiFi communication link and the Bluetooth communication link, realizing time-division multiplexing of the 2.4GHz WiFi communication link and the Bluetooth communication link.

[0031] The first duplexer 131 is connected to the first radio frequency switch 121 and the first antenna 141. The duplexer consists of two sets of bandpass filters of different frequencies, which combine the transmitted signals from the two frequency bands and separate the received signals from the two frequency bands, enabling both frequency bands to share a single antenna for transmission and reception. The antenna is a converter between conducted waves and free electromagnetic waves in space; it can convert electrical signals on a conductor into radio waves for transmission into space, and it can also collect radio waves in space and convert them back into electrical signals.

[0032] OR gate chip 150 is connected to main chip 110 and first RF switch 121 respectively. The function of OR gate is to implement logic and basic operations. If an event occurs as long as one condition is met under multiple conditions, this is the "OR" logic relationship. A circuit with "OR" logic relationship is called an OR gate. In this embodiment of the present invention, when there is a signal at the first 2.4GHz WiFi transceiver port, main chip 110 informs OR gate chip 150, OR gate chip 150 calculates the switching signal internally and sends the switching signal to first RF switch 121, and first RF switch 121 switches to the 2.4GHz WiFi communication link. When there is a signal at the Bluetooth transceiver port, main chip 110 informs OR gate chip 150, OR gate chip 150 calculates the switching signal internally and sends the switching signal to first RF switch 121, and first RF switch 121 switches to the Bluetooth communication link. In this way, time-division multiplexing of the 2.4GHz WiFi communication link and the Bluetooth communication link is realized. Since the calculation of the switching signal is performed by the OR gate chip 150, the computational load of the main chip 110 is reduced. In addition, the OR gate chip 150 performs the calculation of the switching signal specifically, avoiding the problem of complex internal signals and mutual interference in the main chip 110, which could lead to errors in the calculated switching signal. This improves the stability of the 2.4GHz WiFi communication link and Bluetooth communication link and enhances the communication quality.

[0033] The wireless network card provided by this utility model includes a main chip, a first radio frequency switch, a first duplexer, and an OR gate chip. The main chip includes a first 2.4GHz WiFi transceiver port and a Bluetooth transceiver port. The first radio frequency switch is connected to both the first 2.4GHz WiFi transceiver port and the Bluetooth transceiver port. The first duplexer is connected to both the first radio frequency switch and a first antenna. The OR gate chip is connected to both the main chip and the first radio frequency switch. Since the calculation of the switching signal for the first radio frequency switch is performed by the OR gate chip, the computational load on the main chip is reduced. Furthermore, having the OR gate chip specifically perform the calculation of the switching signal avoids the problem of complex internal signals and mutual interference within the main chip, which could lead to errors in the calculated switching signal. This improves the stability of the 2.4GHz WiFi communication link and the Bluetooth communication link, and enhances communication quality.

[0034] In some embodiments of this utility model, such as Figure 1 As shown, the main chip 110 also includes a second 2.4GHz WiFi transceiver port, and the wireless network card also includes a second duplexer 132. The second duplexer 132 is connected to the second antenna 142 and the second 2.4GHz WiFi transceiver port respectively. The WiFi signal of the second 2.4GHz WiFi transceiver port forms another 2.4GHz WiFi communication link. The two 2.4GHz WiFi communication links can serve as backups for each other, improving the communication stability of the wireless network card.

[0035] In some embodiments of this utility model, such as Figure 1 As shown, the main chip 110 also includes a first 5GHz WiFi transmitting port and a first 5GHz WiFi receiving port. The wireless network card also includes a second RF switch 122, which is connected to both the first 5GHz WiFi transmitting port and the first 5GHz WiFi receiving port. A second duplexer 132 is connected to the second RF switch 122. The second RF switch 122 is used to select whether to connect to the first 5GHz WiFi transmitting port or the first 5GHz WiFi receiving port, thereby enabling the transmission and reception of 5GHz WiFi signals.

[0036] In some embodiments of this utility model, such as Figure 1As shown, the main chip 110 also includes a second 5GHz WiFi transmitting port and a second 5GHz WiFi receiving port. The wireless network card also includes a third RF switch 123, which is connected to both the second 5GHz WiFi transmitting port and the second 5GHz WiFi receiving port. The first duplexer 131 is connected to the third RF switch 123. The third RF switch 123 is used to select between connecting to the second 5GHz WiFi transmitting port or the second 5GHz WiFi receiving port, thereby enabling the transmission and reception of 5GHz WiFi signals. The 5GHz WiFi signals from the first 5GHz WiFi transmitting port and the first 5GHz WiFi receiving port form a 5GHz WiFi communication link, and the 5GHz WiFi signals from the second 5GHz WiFi transmitting port and the second 5GHz WiFi receiving port also form a 5GHz WiFi communication link. The additional 5GHz WiFi communication link can improve communication efficiency.

[0037] For example, in the above embodiments, the wireless network card further includes a first IPEX connector 171 and a second IPEX connector 172. The first IPEX connector 171 is connected to a first duplexer 131 and a first antenna 141, respectively, and the first IPEX connector 172 is connected to a second duplexer 132 and a second antenna 142, respectively. An IPEX connector (also known as an IPX or UFL connector) is a miniature radio frequency coaxial connector designed for high-frequency signal transmission and primarily used in compact spaces within electronic devices. Using an external antenna with an IPEX connector can improve signal directionality and anti-interference capabilities.

[0038] In some embodiments of this utility model, such as Figure 1 As shown, the wireless network card also includes an 80MHz passive crystal oscillator 161 and a 32.768KHz active crystal oscillator 162, both of which are connected to the main chip 110. The 80MHz passive crystal oscillator 161 provides the main clock to the main chip 110, and the 32.768KHz active crystal oscillator 162 provides the real-time clock to the main chip 110.

[0039] In some embodiments of this utility model, such as Figure 1 As shown, the wireless network card also includes a power supply circuit (not shown in the figure). The power supply circuit is connected to the main chip 110, the first RF switch 121, the second RF switch 122, the third RF switch 123, and the OR gate chip 150, respectively, providing the voltage required for operation to the main chip 110, the first RF switch 121, the second RF switch 122, the third RF switch 123, and the OR gate chip 150. For example, the wireless network card has a total of 6 power supplies, which are powered by 4 LDO chips and 2 DC-DC step-down chips.

[0040] In some embodiments of this utility model, such as Figure 1 As shown, the main chip also includes a PCIe interface, a USB interface, and a GPIO interface. WiFi communicates with the host computer via the PCIe interface, and Bluetooth communicates with the host computer via the USB interface. GPIO (General Purpose Input Output) is a general-purpose digital input / output port. In embedded systems, GPIO is designed as a flexible pin that can be configured as either input or output to meet different application requirements.

[0041] In some embodiments of this utility model, the main chip 110 is model SCM2625A.

[0042] The wireless network card provided by this utility model can work on domestic operating systems (such as Tongxin Operating System, Galaxy Kylin Operating System, Zhongke Fangde Operating System) and domestic central processing units (such as Phytium, Loongson, Zhaoxin). It supports 22×30mm and 13×15mm package sizes and is widely compatible with existing laptops, desktops, cloud computers, NUCs (Next Unit of Computing) and OPS (Open Pluggable Specification).

[0043] The 22×30mm network card uses a gold finger plug-in installation method, which offers better compatibility and transmission performance. The 13×15mm network card is installed using a stamp hole soldering method, which is more compact and provides a more robust and reliable connection, allowing users to choose according to their needs.

[0044] The wireless network card of this invention was installed in a laptop equipped with a Zhaoxin KX-6000G processor and running the Galaxy Kylin Desktop Operating System V10 (SPI)-2403. WiFi uplink and downlink data transmission tests were conducted in a microwave shielded room. Figure 2 The following is a graph showing the test results of WiFi uplink and downlink data transmission tests on the wireless network card of this utility model. Figure 2 As shown, the maximum uplink and downlink transmission rates of WiFi both exceed 900Mbps and remain stable for 60 seconds without significant fluctuations. This indicates that the wireless network card of this invention can not only maintain a transmission speed close to gigabit broadband in a domestic operating system, but also has excellent stability.
