Micro Harmonics HC100 WR-10 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 more than triple 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
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 the symmetry if needed.
