Abstract :
The criteria for selecting ferrite materials for broadband circulator applications are discussed. Transmission measurements in a circulator-like microstrip fixture are used to select materials for applications in a given frequency band. Data concerning the frequency dependence of transmission loss in the partially magnetized state at various values of bias field are presented
