LTE Standard Module Series EC25 Mini PCIe Hardware Design Figure 17: Referenced Heatsink Design NOTES 1. 2. The module offers the best performance when the internal BB chip stays below 105°C. When the maximum temperature of the BB chip reaches or exceeds 105°C, the module works normal but provides reduced performance (such as RF output power, data rate, etc.).
