製品概要

概要

STSW-ST25R004 contains a graphical user interface (GUI) to specify the antenna parameters and the target matching. It performs transient, AC, and S-parameter simulations of the calculated antenna schematic.

An online version of the tool is available at https://eds.st.com. This is part of the ST eDesignSuite, an easy-to-use comprehensive software helping customers during their design.

AN4974 and AN5276 (available on www.st.com) provide guidance on the measurement of the antenna parameters required as input for this matching tool. With these inputs the best matching circuit can be defined.

  • 特徴

    • STSW-ST25R004 is a software that calculates the matching network for antennas connected to ST25R39xx/39xxB devices, using Qucs (Quite Universal Circuit Simulator) to simulate the antenna and the matching network characteristics.
    • The software supports the following products:
      • ST25R3911B
      • ST25R3912
      • ST25R3914
      • ST25R3915
      • ST25R3916 / ST25R3916B
      • ST25R3917 / ST25R3917B
      • ST25R3918
      • ST25R3920 / ST25R3920B
