Abstract

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> We present new results for a two-port vector network analyzer swept-frequency test set for the 325–508 GHz frequency band. The calibrated dynamic range performance in the full frequency band is discussed. Using a line–reflect–line calibration procedure, the dynamic ranges for return and insertion losses of better than <formula formulatype="inline"><tex>$-$</tex></formula>20 and <formula formulatype="inline"><tex>$-$</tex></formula>35 dB, respectively, are achieved. We examine the performance of the calibrated test set for the first time by measuring S-parameters of passive waveguide components and comparing data with electromagnetic simulations. </para>
