798 Microwave Ltd.

                           specializing in isolators and circulators since 1960

For more than 50 years, 798 Microwave Ltd. has been dedicated to the design and manufacture of microwave ferrite components, specializing in high power isolators, circulatorsattenuators and terminations.

We have pulse power transmitter for high power device test (S band 1MW, X band 250kW and Ku band 80kW) for high power device test. More our customerized production is widely used in satellite communication, radar, navigation, radio and television, microwave communications, wireless communications, electron accelerator systems.

    Our expertise is the higher power device by custom-made. In-house ferrite materials facilities, computer-aided design, and experienced research and development teams, allow 798Microwave to offer customers specific designs with optimal features.
    Our 4-port differential phase shift circulators is designed for use in high-peak power applications. For example, in electron accelerator systems,it is used as the protector for the magnetron work normally on the condition of large reflection power.
