Data Sheet Rev.D, Oct 07, 2021 | Subject to change without notice 4 of 8 www.qorvo.com Evaluation Board Assembly Drawing Note: Vias are required under the backside paddle of this device for proper RF/DC grounding and thermal dissipation. A via drill di ameter of 0.4mm and a minimum via wall copper plating thickness of 25um is recommended. Open vias are preferred to allow flux and g ases to escape during reflow soldering and therefore to minimize voiding. Underneath this via array a heat sink with thermal grease needs to be placed which is able to dissipate the complete module DC power (up to 5 Watts). In any case the module backside temperature should not exceed 110 °C.
