RFchips are core components of navigation terminals, directly affecting the overall performance of terminal products. As the BeiDou satellite navigation system becomes more widely used, the demand for RFchip testing has surged. Traditional testing methods can no longer meet the increasing requirements for high efficiency and precision.
