Data Sheet Rev.F, June 7, 2017 | Subject to change without notice 7 of 10 www.qorvo.com RFAM3620 Temperature Sensing Feature The RFAM3620 provides an internal NTC resistor for temperature sensing. This resistor is located right next to the output transistor stage. Within the application circuit the NTC is part of a voltage divider. The output voltage of the voltage divider (Vt) can be correlated to the module backside temperature.

Data Sheet Rev.F, June 7, 2017 | Subject to change without notice 9 of 10 www.qorvo.com PCB Metal Land Pattern (Dimensions in millimeters) RECOMMENDED LAND PATTERN RECOMMENDED LAND PATTERN MASK Notes: 1. All dimensions are in millimeters. Angles are in degrees. 2. Use 2 oz. copper minimum for top and bottom layer metal. 3. Vias are required under the backside paddle of this device for proper RF/DC grounding and thermal dissipation. We recommend a 0.35mm (#80/.0135") diameter bit for drilling via holes and a final plated thru diameter of 0.25mm (0.10”). 4. Ensure good package backside paddle solder attach for reliable operation and best electrical performance. 5. Place mounting screws near the part to fasten a back side heat sink. 6. Do not apply solder mask to the back side of the PC board in the heat sink contact region. 7. Ensure that the backside via region makes good physical contact with the heat sink. 10.80REF 10.80REF A A A A A A A AA A A A A AAA A A AAA 2.500 3.500 0.625 1.875 3.125 4.750 5.100 DETAIL A PAD 21x THIS ROTATION 0.600 0.600 4.320 4.200 4.200 4.200 2.500 1.250 3.500 4.750 5.100 A A A A A A A A AA A A A A AAA A A AAA 2.500 3.500 0.625 1.875 3.125 4.750 5.100 DETAIL A PAD 21x THIS ROTATION 0.700 0.700 4.370 4.250 4.250 4.250 2.500 1.250 3.500 4.750 5.100 A 10.90REF 10.90REF
