Abstract :
This paper presents the design and fabrication of a new self-balancing DC-substitution bolometric bridge for RF power measurement with the aim of renewing the systems available in the RF and microwave standards laboratory at LNE. This new RF power meter allows us to provide more reliability in RF power measurements for our primary standards calibration based on microcalorimeters as well as for our customers power meter calibrations. The power meter includes a new electronic circuit design based on charge transfer and an adjustable reference resistance for bolometric/thermistor sensor mismatch minimization.
