The microwave signal is amplitude-modulated using the PIN modulator. When limited to a modulation frequency, detection can be carried out in very narrow bandwidths. The effects of noise and interference remain small, the sensitivity of the measurements is improved. The PIN modulator can be used in the linear characteristic range as an analog amplitude modulator and in switching mode for digital modulation.
