Abstract :
Filters incorporating asymmetric stripline Y-junction circulators have been fabricated and tested over the frequency range of 0.05 to 18 GHz. The passband frequency was near 2 GHz. The insertion loss was ~2 dB and the stopband extended from 4.5 to 18 GHz with transmission ⩽-30 dB. The filter includes ferrite discs in which high order modes have been eliminated as calculated in an earlier paper
