Frequently Asked Questions
Which frequency bands does the ATA8520E-GHQW support, and what LPWAN protocol does it implement?
The ATA8520E operates in the 868 MHz band for Europe and the 902 MHz band for North America, implementing the SIGFOX narrowband LPWAN protocol. This ultra-narrowband approach provides link budgets exceeding 140 dB, enabling transmission ranges of 10 km to 40 km in open environments with transmit power typically around 14 dBm to 22 dBm.
How does the FCC certification on the ATA8520E-GHQW accelerate product development timelines for IoT device makers?
Because the ATA8520E carries pre-obtained FCC certification, product developers can integrate it into their designs without conducting separate RF module-level emissions testing for the US market, potentially saving 4 weeks to 12 weeks of regulatory lab time and thousands of dollars in testing fees before product launch.
What package does the ATA8520E-GHQW use, and how does its construction benefit RF signal integrity?
The device is housed in a 32-pin VQFN package with a central heat slug, measuring approximately 5 mm × 5 mm. The exposed pad provides a solid RF and thermal ground plane connection, improving transmit efficiency and heat dissipation in compact PCB designs, which is critical for maintaining consistent output power levels during continuous sensing cycles.
