If you’re looking for an alternative to the surface mount Circulator JCM3300T3800S10R, Digi-Key carries a couple of similar devices.
1. MPN # 0735912048
2. MPN # 0735912049
Apart from these, we also have two more Circulators for the same frequency with slightly different “Isolation” values: MPN# SKYFR-001822 and MPN# SKYFR-001823.
