Abstract

We present a method for improving high-insertion-loss measurements with a calibrated vector network analyzer (VNA) requiring only two additional pieces of hardware. By utilizing an amplifier and an attenuator, and measuring wave-parameters rather than scattering-parameters, we are able to increase the dynamic range of our measurements while decreasing uncertainties due to the noise floor of the VNA. We compare the results of our technique to standard methods for insertion-loss values up to 110 dB.
