BLA31AG300SN4D Frequently Asked Questions (FAQs)

  • Murata recommends a PCB layout with a solid ground plane and a minimum of 10mm clearance around the antenna to ensure optimal performance.
  • The antenna can be tuned by adjusting the length and width of the PCB traces connected to the antenna, as well as the placement of nearby components. Murata provides a tuning guide in their application notes.
  • The maximum power rating for the BLA31AG300SN4D is 10W, but it's recommended to derate the power to 5W or less for continuous operation to ensure reliability.
  • While the BLA31AG300SN4D is optimized for 2.4GHz, it can be used for other frequency bands with some degradation in performance. However, Murata recommends using a different antenna model for optimal performance in other frequency bands.
  • Murata recommends using a reflow soldering process with a peak temperature of 260°C or less, and ensuring that the PCB pads are clean and free of oxidation.
