856671 Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the RF traces short and away from the digital lines. Use a 50-ohm microstrip line for the RF output.
  • Use a high-impedance biasing circuit with a low-pass filter to minimize noise. Ensure the bias voltage is stable and within the recommended range (2.7-3.3V).
  • The recommended operating temperature range is -40°C to 85°C. However, the device can operate up to 105°C with reduced performance and reliability.
  • Use a π-network or a T-network matching circuit to match the device's output impedance to the load impedance (typically 50 ohms).
  • Use a human-body model (HBM) ESD protection circuit with a minimum of 2 kV rating. Ensure the PCB layout and handling procedures minimize the risk of ESD damage.
