What is a waveguide isolator?

A waveguide isolator allows signal flow in one direction only, protecting amplifiers and transmitters from reflected power. It is typically implemented using a circulator with a terminated port.

What frequency range do Mi-Wave waveguide isolators cover?

Mi-Wave waveguide circulators used as isolators cover 18–110 GHz in Y-junction (Series 180) and multi-junction (Series 179) designs.

Millimeter Wave Waveguide Circulators & RF Isolators

Mi-Wave’s millimeter wave circulator range consists of passive 3-port waveguide RF devices that control signal direction and flow within an RF circuit. Each millimeter wave circulator routes energy from each port to its clockwise adjacent port in a unidirectional fashion — made possible through ferrite materials and permanent magnets that set the signal flow direction. Mi-Wave circulators are available in Y-Junction (Series 179) and Multi-Junction (Series 180) configurations from 18–110 GHz.
