Abstract :
A new multiband multiport circuit is presented in this letter. This circuit, designed for microwave phase detection applications, can be used in multiband direct conversion front-ends, phased-array antenna drivers or other microwaves amplitude or phase measurements. A complex vector, named Γ, based on multiport output voltages, is introduced for direct RF phase measurements. An excellent match of simulation and measurement results is obtained in all frequency bands.
