Micro Harmonics HC80 WR-8 Hybrid Circulator

The patent-pending hybrid circulator is designed for wideband millimeter wave transmit/receive systems. The hybrid circulator is an innovative technology, combining an orthomode transducer with a Faraday rotator to achieve five times the bandwidth of the traditional Y junction design. Every circulator is tested on a vector network analyzer to ensure conformity, and the test data is provided to the customer.

Asymmetry
Asymmetric Insertion Loss Unlike the Y junction circulator, the hybrid circulator is asymmetric. The path from port 3 to port 1 is internally terminated, as shown in the schematic
to the right and verified by the S13 trace in the measured data below. On request, the hybrid circulator can be assembled in a way that restores symmetry if needed.
