【 摘 要 】

References(2)Cited-By(1)To establish an RF power standard above 110GHz, we have developed a measurement system using a down-conversion mixer with a spectrum analyzer, and the conversion loss of the mixer was determined by the three-mixer method. This method measures the three transmission S-parameters (S21) of three mixer pairs using a vector network analyzer. The experimental results proved that the three-mixer method can determine the conversion loss of mixers with an uncertainty of 0.5dB (level of confidence: 95%) in the entire range of the D-band. Using this uncertainty and the uncertainty of the spectrum analyzer, the proposed system can measure the RF power in the D-band with an uncertainty of less than 2.0dB.
