Laboratory has microcalorimeter system which is able to measure effective efficiency of the thermistor mounts with N type connector and WR220 connector in the frequency range of 100 kHz - 18 GHz and 18 GHz - 26.5 GHz respectively.

Also, calibration factor of the power sensor and thermistor mount which have N type, 3.5mm and 2.92 mm connectors in the frequency range of 100 kHz - 18 GHz, 100 kHz - 26.5 GHz and 100 kHz - 40 GHz respectively can be measured. In the scope of the power measurements, the power accuracy, linearity and flatness measurement of microwave power generator in the 100 kHz - 40 GHz frequency and -70 dBm -+20 dBm power range can be achieved.

Transmission and reflection parameters that is used to characterize the microwave circuit component measurement in the 100 kHz - 50 GHz frequency range can be achieved for N type, 3.5 mm and 2.4 mm connectors.

Fundamental quantities, measurement conditions and expanded uncertainties belongs to the measurements done at the laboratory are given below.
