Evaluation and Demonstration Boards and Kits are designed to enable engineers, developers and enthusiasts to easily evaluate and demonstrate products. The WAU8812EVB is among these boards and kits. In this article, we will look at its application field and working principle.

The WAU8812EVB is an evaluation board based on the WAU8812 chipset. The chipset combines the latest 2.4GHz frequency band RF transceiver and advanced MAC-baseband Technologies into a single-chip solution to enable 802.11b/g/n protocols. It also supports MIMO 2x2 operation with two antenna ports. The WAU8812EVB is a reference design to demonstrate the performance of the WAU8812 chipset for wireless applications, including access points, routers and consumer electronics products.

The WAU8812EVB also provides a comprehensive solution to evaluate the performance of the WAU8812 chipset. Its development board includes a complete reference design including a 20 MHz crystal oscillator, a MIMO 2x2 JTAG connector, one SMA antenna connectors, one 2.4GHz RF mini-circuit, two mini-circuits, two mini-circuits, two output enable JKFFs, one FR SMD capacitors, one output buffer, one TCXO, and one RJ-45 jack. It also includes a full evaluation kit including one WAU8812EVB, an evaluation board, a power cable, a network cable, two power buttons, two antenna connectors, and one programming cable. The evaluation kit further includes one USB Flash drive containing the necessary code and documentation to evaluate the WAU8812 chipset\'s performance.

The WAU8812EVB board operates in a frequency band of 2.4–2.5 GHz. This frequency range is reserved for short-range, datalink specific wireless applications such as Wi-Fi. The board is designed with a single-chip implementation of the WAU8812 chipset, including an integrated 802.11b/g/n MAC, baseband, analogue and RF circuitry. It also features a high-performance radio transceiver to allow for higher-data rate signal transmission over longer distances. A significant aspect of the board is its MIMO 2x2 operation, offering two outputs from a single single antenna.

The WAU8812EVB board\'s working principle is straightforward. The application begins by inputting the desired settings into the board, such as channel selection, antenna configuration, and other necessary parameters. This is done through the USB interface or through a web based UI. The board then begins to encode the signal as specified by the given parameters, before transmitting it via the integrated RF circuitry and antenna. The board also handles reception of data, as well as signal sensitivity and reception quality checks. Finally, all data produced is sent back to the user via the USB interface or via the web based UI.

The WAU8812EVB is a highly capable evaluation board and evaluation kit for testing the features and performance of the WAU8812 chipset. It integrates the latest chip technologies and advanced MIMO 2x2 operation, enabling highly efficient wireless signal transmission and reception. The board is easy to use and provides a comprehensive solution for testing the performance of the WAU8812 chipset. With its comprehensive hardware and software, the board offers a wide range of applications, making it the ideal tool for evaluating and demonstrating the WAU8812 chipset for wireless applications.
