  • An interferometric IQ-mixer/DAC solution for active, high speed vector network analyser impedance renormalization
    Publication number: 20190391193
    Abstract: Device under test (DUT) interface device for use in a system for executing measurements on a device under test (9) with a vector network analyser (11). The DUT interface device comprises a divider/coupler component (4), a variable gain amplifier (5), an I/Q mixer (6) and a bridge/coupler component (7) and provides a test signal (a) to the DUT terminal (3). The system further comprises a control unit (12) connected to the vector network analyser (11) and to control input terminals (8) of associated ones of the at least one DUT interface device (1). The control unit (12) provides quadrature control signals (VI, VQ) for the associated at least one DUT interface device (1), which are connected directly to the device under test (9). The present invention further relates to proper calibration and measurement methods.
