5.4 Heat Sink and Temperature

Users are strongly encouraged to use the xWR6843AOPEVM with the heat sink installed. Due to the smaller size of the xWR6843AOPEVM, it is likely to get warmer than other larger sized EVMs on the mmWave Radar portfolioso care must be taken to ensure the junction temperature does not exceed 105°C. Figure 5-4 shows measurement of junction temperature versus duty cycle taken with and without the heat sink. As seen in the plot, the EVM can safely operate up to 50% duty cycle with or without the heat sink. Although the heatsink is not absolutely required, usage of the heat sink provides protection against exceeding the junction temperature at higher duty cyles.

When using the EVM for custom applications, the duty cycle can be adjusted as needed, the heat sink provided with the kit can be used, customers can also design their own heat sink using better heat disippating materials or one with more surface area such as addition of fins. The CAD drawing for the heat sink is shown in Figure 5-5

Application of the heat sink is shown in Figure 5-6
