Abstract

This contribution provides techniques for accurately characterizing the measurement uncertainty due to chamber setup for total radiated power measurements at millimeter-wave frequencies. The setup is based on the reverberation chamber as a well-known measurement environment capable of performing total radiated power measurements of wireless devices. We showed that by applying various stirring techniques it is possible to reduce the random component of measurement uncertainty close to 2%. We used a model for estimating the uncertainty due to chamber set-up for total radiated power measurements based on the K factor which was compared to uncertainties calculated from relative power measurements and showed excellent agreement. We performed a significance test to confirm that the uncertainty due to the lack of spatial uniformity dominates over the uncertainty due to the limited number of mode-stirring samples. The observed uncertainty was compared to an ideal chamber situation and showed good agreement.
