Mi-Waves’ 172F series is an H-plane, 3 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.

The 172F series isolators are available in standard WR-42, WR-28 and WR-22 waveguide sizes from 18.0 to 50.0 GHz.


The 172F series Y-junction isolators are useful in test setup and operational systems.

These devices provide a high degree of isolation between signal sources and system loads by sharply attenuating reflected signals with very low loss in the forward direction.
