Waveguide Tuners And Attenuators

These precision waveguide attenuators utilize high density shaped microwave-absorbing elements permanently attached to a standard waveguide section. The VSWR of the fixed attenuators is less than 1.10:1 over a 10% band and the variable units exhibit a 1.15:1 maximum VSWR. When requested, calibration charts traceable to the National Bureau of Standards can be supplied.

For extremely high power or for low loss applications, hybrid type variable waveguide attenuators are available. These units have a minimum insertion loss of 0.05 dB nominal and can be varied to 30 dB attenuation under full transmitter power.

When phase shift with attenuation causes signal degradation, MEGA INDUSTRIES will supply constant phase, variable power dividers for special system applications.

Waveguide Tuners

These multi-screw waveguide tuners remove a 1.5:1 VSWR over a limited bandwidth at any phase angle for subsystem optimization. We offer five probe tuners; three probe tuners, and E-H waveguide tuners that are pressure tight and are particularly suited for system applications where accurate, but infrequent adjustments must be made to system VSWR and phase.

Our technical staff will be pleased to assist you in preparing specifications for your microwave transmission system tuning requirements.
