“…It allows the experimental determination of effective efficiency of thermal power sensors (i.e., bolometric and thermoelectric sensors). [15][16][17][18] through the DC substitution technique (i.e., applied microwave power is compensated by an appropriate reduction of DC power). As shown in Figure 5, the design of a waveguide microcalorimeter at NIM, China, is based on a twin-line structure with a symmetrically located inactive mount (i.e., a "dummy" thermistor mount) as the temperature reference.…”

“…As introduced previously, a Type IV power meter was used as a bolometer bridge. The correction factor g of NIM's microcalorimeter was characterized through the measurements where a foil short was inserted between the test port and the DUT in the microcalorimeter [16]. New Trends and Developments in Metrology observed preliminarily.…”

In this chapter, precision power measurement, which is probably the most important area in RF and microwave metrology, will be discussed. Firstly, the background of RF and microwave power measurements and standards will be introduced. Secondly, the working principle of primary power standard (i.e., microcalorimeter) will be described, followed by the discussions of direct comparison transfer technique. Finally, there will be some discussions about the performance evaluation and uncertainty estimation for microwave power measurements.

“…The measurements were performed in the NIM WR22 microcalorimeter [14]. The devices under test were measured four times for SN 216 and eight times for SN 048, respectively, with disconnect and 180 • rotation of the device between each connection.…”
