Abstract :
The evaluation of the 3-port circulator using differential-input operational amplifiers has been performed by scattering-matrix analysis. The s parameters are easily determined over the frequency range tested (1¿300 kHz) and accurately depict the transmission and reflection properties of the circulator.
