  • 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.

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

    主要特性

    • STSW-ST25R004 is a software that calculates the matching network for antennas connected to ST25R3911B/ST25R391x devices, using Qucs (Quite Universal Circuit Simulator) to simulate the antenna and matching network characteristics.
    • The software supports the following products:
      • ST25R3910
      • ST25R3911
      • ST25R3911B
      • ST25R3912
      • ST25R3913
      • ST25R3914
      • ST25R3915
      • ST25R3916
      • ST25R3917
