Cryogenic Isolators / Circulators

Select Model

4-12 GHz Triple Junction Isolator/Circulator

4-12 GHz Triple Junction Isolator/Circulator

Frequency Range 4 – 12 GHz
Insertion Loss 0.5 dB typical
Isolation 50 dB typical
Port Match 17 dB typical
Body Gold-plated OFHC copper
RF Connectors Female SMA

Maximum isolation across the 4–12 GHz band, 50 dB in a single housing for applications where dual junction coverage of this band is insufficient.
0.5 dB insertion loss across a wideband 4–12 GHz range represents a significant engineering challenge. Three stages in one OFHC copper module with full thermalisation at each junction
Available in multiple configurations: triple isolator, triple circulator, and mixed junction combinations to suit signal routing requirements
