“…One of the most demonstrated power measurement techniques is the calorimetric technique which is frequency independent [3], [4], and uses matched-load usually made of absorptive materials on tapered sections. Sensor elements employed include thermoelectric (single load [5], dual load [6], quasi twin [7]) or bolometric (thermistor [8], thin film [4], [9]) types. Such loads are also used as power-absorbing terminals in a twin-load configuration [10], [11].…”

A bolometric thin-film based transfer standard with a novel structure for absolute power detection in D-band (110 -170 GHz) is reported. It uses a resonance-type matching technique with thin-film resistive lines. The same line functions as the sensing element. The change in the resistivity of the line under the incident wave is calibrated to measure the absolute RF power in the D-band. This paper presents the analysis using equivalent circuit models, the full-wave electromagnetic design, the fabrication and the comprehensive characterization of the device. The comparison between a single and a folded-line matching structure is performed, showing the wideband capability of the latter. The transfer standard consists of two sensors in one waveguide housing for RF power measurement, as well as for monitoring and calibrating out the ambient temperature variation. It has shown a very good short-term time response with only ~0.19 % deviation in a given time interval, which is very close to a commercial PM5 sensor with ~0.27 % deviation. The long-term time response is also impressive, with a deviation of less than 0.6 %, similar to a commercial PM5 sensor. The fast response time, good thermal isolation and ambient compensation ability make it suitable for transfer/working standards, which can be used in ambient temperature environments.
