PROJECT TITLE :

Millimeter-Wave Thermoelectric Power Transfer Standard

ABSTRACT:

This paper describes a thermoelectric waveguide power sensor for the frequency range seventy five–a hundred and ten GHz, that has been calibrated in a very waveguide twin-sort microcalorimeter. The sensor is appropriate as a transfer commonplace to supply traceablity for top-frequency power calibrations. The look and calibration of the sensor are described. The calibration relies upon a unique measuring quantity, referred to as generalized potency. The results of mirocalorimeter measurements and sensor performance are given. The new transfer sensor is tested against typical thermistor waveguide sensors during a direct comparison setup, showing sensible agreement among the estimated uncertainties.
