D-Band Waveguide Isolator 110-170 GHz
This D-Band waveguide isolator covers the 110-170 GHz frequency range and provides robust signal isolation for demanding millimeter-wave applications. The WR6 component delivers performance characteristics suitable for next-generation communication systems, aerospace platforms, and laboratory measurement setups requiring precise RF signal management in the sub-terahertz spectrum.
The isolator addresses the growing need for reliable non-reciprocal components as system designers push toward higher frequency bands for increased bandwidth and directional signal control. Integration of such devices becomes critical in complex RF chains where reflected power and signal leakage must be minimized to maintain system stability and measurement accuracy.
Technical Specifications
