Description

The PEWIR1004 is a Waveguide Faraday Isolator offering 25 dB minimum isolation over the full Q band frequency range of 33

to 50 GHz. In a conventional isolator design, three or four parts would be needed to cover the full WR-22 band to achieve this

level of isolation. The Faraday design achieves high isolation with wide band performance. This gold plated WR-22 waveguide

component uses UG-383/U round cover flanges on all ports and has a power rating of 1 watt in the forward direction.

Pasternack Enterprises offers a wide variety of isolators and Waveguide Isolators to fit your needs. These are two-port devices

that transmit microwave or radio frequency power in one direction only and block the signal in the opposite direction. They

can be thought of as a diode for RF energy. Isolators are used to isolate equipment from the effects of conditions outside of

the equipment. For instance they are used to prevent a microwave source being detuned by a mismatched load. Pasternack’s

waveguide isolators feature excellent insertion loss, full WR band high isolation and reliability.
