Operation

Operation

Protest Flanges Care should be taken to protect the face of the flange from any damage that would prevent close surface-to-surface contact. Any burring, denting, or scratching will increases RF leakage and the reflection coefficient of the joint. The supplied plastic cover should be used to protect the flange when the adapter is not in use.

Assemble Carefully When connecting an adapter to a waveguide.

1.Make sure the rectangular ports are oriented the same way (i.e., not "cross-guided").

2.Align ports carefully to minimize reflections.

3.Clamp or bolt flanges securely together so that pressure is evenly distributed over the contacting surfaces. Loose joints and flange distortion result in leakage and mismatch.

Connector Types

Type N Connectors

 

Two versions of the Type N coaxial connector are used on the adapters: one

 

is used on the 281A model, and the other is used in the Option 13B model.

 

The version on the 281A model is plated brass and is compatible with

 

connectors conforming to MIL-C-71. The version on the Option 13B model

 

is stainless steel and is compatible with connectors conforming to MIL-C-71

 

or MIL-C-39012. Dimensions of these connectors are given in Figure 2.
