Y-Junction Isolators
Mi-Wave’s 178 series is an H-plane, three-port Y-junction ferrite device with one arm internally terminated in a matched load . Reflected energy is circulated into this load to isolate the input . All external mating surfaces are machined to extreme flatness to provide connection to standard waveguide flanges for minimum discontinuity.
Note: Our website contains just a few types of Isolators we build. Consult with us for your specific needs.
