Many experiments have been proposed in order to demonstrate that the "five-port" system performs a homodyne demodulation . The large bandwith of a five-port circuit is its main advantage. However, this kind of system must be calibrated for each frequ

This paper presents a homodyne five-port network analyzer operating at 94 GHz using a single five-port junction. The homodyne detection is realized using a PIN diode amplitude modulator and an AC detection technique. The obtained results show that th

This paper presents a convenient calibration technique of a six-port reflectometer requiring a set of loads including two standards and avoiding the use of an open circuit. This method has been applied for different reflectometers at three frequencie

An active load-pull measurement system using two six-port reflectometers operating in the W-frequency band is demonstrated. Ninety loads over the whole Smith chart have been synthesized and measured by both reflectometers. The maximum deviation betwe

A new range/relative-speed sensor for automobiles is shown. Based on the six-port phase/frequency discriminator, it determines distance and Doppler frequency by means of the phase difference between transmitted and received signals. It presents sever

The use of the Fabry-Perot resonance in direct internal electrooptic probing reveals a new calibration method. Substrate resonances modulated by the Pockels effect results in a direct amplitude modulated electrooptic signal. The relation between this

An original measurement system for nonlinear microwave power-transistor characterization using six-port reflectometers is presented. It allows independent active tuning of the output impedances at f/sub 0/ and 2f/sub 0/ (multiharmonic load-pull) and

In this paper a new method to calculate the noise parameters of transistors T/sub i/ (MESFET or HEMT) as a function of gatewidth and drain-bias current is presented. This method needs the knowledge of the R, P, and C coefficients. It is based on the
