Description
Summary:A novel millimeter-wave to submillimeter-wave instrumentation setup for the characterization of transceivers and their functional building blocks dedicated to 6G Terahertz communication is presented. The measurement system comprises wideband frequency up- and down-converters into the WR10 and WR3.4 bands, coupled to a novel directional coupler which allows for the calibration of wideband complex modulated signal in terms of vectorial signal distortion in the RF domain. Using predistortion of the baseband input signal, the calibration plane can be shifted to the input and to the output of a device-under-test. We present the input and output-related calibration of solid-state power amplifier modules at a center frequency of 77.5 GHz for QPSK and 256-QAM modulation with 1 and 4 GBd symbol rates as well as at 300 GHz for QPSK and 64-QAM modulation with 16 GBd and 1.6 GBd symbol rates, respectively. The calibration in the RF domain reduces the error-vector-magnitude by an order of magnitude.
