Abstract

This paper presents a fast responding frequency measurement system based on Six-Port technology being able to determine precisely the frequency of very short time domain pulses of 1 μs and even less in the 2.4 GHz ISM band. By using a delay line the frequency measurement can be reduced to a phase measurement that can be quickly evaluated by the Six-Port network implemented with lumped components. Measurements show that the delay line, currently realized by a SMA cable, is extremely sensitive to temperature variations even in the range of 0.1 K. Thus, a temperature compensation method based on reference measurements is proposed and final measurements show that the system can reach a calibrated and temperature compensated error of only a few parts per million (ppm).
