RF testing device and system, and calibration method for RF transmission characteristics

Abstract

An RF testing device, system, and calibration method for RF transmission characteristics applicable to an OTA (Over-the-Air) testing environment are provided. The RF testing device includes an RF generator, a main channel, a measurement channel, and a receiver. The RF generator provides a test signal in the millimeter-wave band. The main channel is electrically connected to the RF generator and is used to connect a device under test (DUT) and transmit the test signal to the DUT. The measurement channel is used to sense an RF signal radiated by the DUT. The receiver is electrically connected to the main channel and the measurement channel and is used to calculate the RF transmission characteristics of the DUT based on the RF signals.
