PA85 Frequently Asked Questions (FAQs)

  • Apex recommends a 4-layer PCB with a solid ground plane, and thermal vias under the package to dissipate heat. A thermal pad on the bottom of the package should be connected to a heat sink or a thermal management system.
  • Apex recommends using a bias circuit with a voltage regulator and a temperature compensation network to ensure stable biasing. The recommended bias voltage is 5V, and the quiescent current should be set to 150mA.
  • Apex recommends using a conjugate match at the input and output ports to achieve optimal power transfer. A 1:1 impedance ratio is recommended, and the matching network should be designed to compensate for the package parasitics.
  • Apex recommends using voltage and current limiting circuits to protect the PA85 from overvoltage and overcurrent conditions. A voltage clamp or a crowbar circuit can be used to limit the voltage, and a current sense resistor with a shutdown circuit can be used to limit the current.
  • Apex recommends operating the PA85 within a temperature range of -40°C to 85°C. The device is designed to operate within this range, and exceeding this range may affect its performance and reliability.
