Qorvo provides a recommended PCB layout in their application note AN-2171, which includes guidelines for component placement, trace routing, and grounding to minimize parasitic inductance and ensure optimal performance.
The QPA9801TR13 requires a specific biasing scheme to achieve optimal linearity and gain. Qorvo recommends using a voltage-controlled current source to bias the amplifier, with a typical bias voltage of 3.3V and a bias current of 40mA. Refer to the application note AN-2171 for more details.
The QPA9801TR13 is rated for operation from -40°C to +85°C, but Qorvo recommends derating the device for reliable operation above +70°C. Consult the datasheet for more information on temperature derating.
The QPA9801TR13 is a sensitive device and requires proper ESD protection during handling and assembly. Qorvo recommends using ESD-safe handling procedures, such as wrist straps and anti-static mats, and incorporating ESD protection devices, such as TVS diodes, into the PCB design.
Qorvo recommends a peak reflow temperature of 260°C for the QPA9801TR13, with a recommended soldering profile of 3°C/sec ramp-up, 30-second dwell time, and 6°C/sec ramp-down. Consult the datasheet for more information on soldering guidelines.
