281A/B Adapters Operating and Service Manual5

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.
