Qorvo provides a recommended PCB layout and land pattern in their application note AN-2171, which can be found on their website. It's essential to follow these guidelines to ensure optimal performance and minimize parasitic effects.
The QPQ1905TR13 has a thermal pad on the bottom, which should be connected to a thermal ground plane on the PCB. A thermal via array can be used to dissipate heat to the opposite side of the board. Additionally, a heat sink or thermal interface material can be used to further improve thermal management.
While the datasheet specifies an operating temperature range of -40°C to 85°C, Qorvo recommends derating the device's power handling capabilities above 70°C to ensure reliable operation. It's essential to consider the specific application's temperature profile and derate accordingly.
The QPQ1905TR13 has a nominal impedance of 50 ohms. To match the impedance, use a pi-network or a T-network topology with capacitors and inductors. Qorvo provides a matching network design guide in their application note AN-2171, which can be used as a starting point for impedance matching.
Qorvo recommends using a reflow soldering process with a peak temperature of 260°C and a dwell time of 20-30 seconds. The device is compatible with Pb-free soldering processes, and it's essential to follow the recommended soldering profile to prevent damage to the device.
