Abstract :
The concept of a network for the measuring system of a scattering matrix of two-ports is presented. The network contains only two power meters instead of eight as in the classic dual six-port technique. The proposed design is not only more economical (fewer power meters) but also more accurate due to long-term instability of sensitivity. The main advantage of this circuit is the possibility of microwave pulse excitation. This circuit could be applied for measurement of power transistors in pulsed mode
