DLFCN-290+ Frequently Asked Questions (FAQs)

  • Mini-Circuits recommends a ground plane on the bottom layer, and a microstrip layout on the top layer with a 50-ohm impedance. Keep the filter away from other components and avoid vias near the filter.
  • Use a pi-network or a T-network to match the filter's 50-ohm impedance to your system's impedance. You can also use a Smith chart to design the matching network.
  • The DLFCN-290+ can handle up to 10W of continuous power, but it's recommended to derate the power handling based on the operating frequency and temperature.
  • The filter is rated for operation up to 85°C, but the performance may degrade at higher temperatures. Consult with Mini-Circuits for custom high-temperature designs.
  • Use a compatible connector or solder the filter directly to the PCB. Ensure the PCB material and layout are compatible with the filter's frequency range and power handling.
