Abstract: A new, simple method for precise TVRO LNC (Television Receive Only Low Noise Converter) noise factor measurement is proposed in this paper. In this manner, the systematic measuring error due to the presence of coaxial/waveguide adapter is eliminated. The measurement procedure is developed using microwave measuring system for noise factor measurement based on the noise figure meter HP 8970B, opt. H18.
Key words: Measurement, noise factor measurement, low noise converter, microvawe circuits.
