Abstract
This paper describes a recently developed V-band waveguide microcalorimeter that serves as primary power standards at the Korea Research Institute of Standards and Science (KRISS). The design scheme of the waveguide microcalorimeter is presented, and its basic performance is evaluated. The stability of the thermopile module of the microcalorimeter at ambient temperature is measured, and appropriate parameters obtained from a linear modeling are employed to compensate the temperature drift. The thermal performance of an adiabatic waveguide is simulated using a finite-element-method-based tool. A dedicated high-power V-band source module is developed, and its stability and repeatability are evaluated. In order to determine the correction factor of the microcalorimeter, the offset-short method was used and the results are presented. The uncertainty budget of a V-band reference standard at selected frequencies is presented.
