Abracon ACR1504I3-EVB Evaluation Boards are designed to evaluate the ACR1504I3 chip antenna. With typical operating frequencies of 915MHz / 868MHz / 433MHz, the chip can be used for 915MHz / 868MHz / 433MHz LPWA/ISM applications. To evaluate antenna performance, engineers can calibrate the vector network analyzer (VNA) for the testing frequency band and connect the ACR1504I3-EVB to the calibrated port using the SMA connector included on the board. Abracon ACR1504I3-EVB Evaluation Boards are RoHS/RoHS II compliant and feature dimensions of 105mm x 35mm x 1mm.
