Bird 1000-WA-MFN-30 Innards

If anyone's interested, the attached photo shows the innards of this 1kW rated 30dB attenuator, supposedly useable at up to 1GHz.

Mine failed when the input connector went intermittently open circuit.  Turned out the connector was one of those with a very thin tab milled onto it for PCB stripline connection.  With no stress relief of any kind provided, it eventually snapped.  Replaced with a bit of copper tape soldered to connector and input line, and although I may have lost a smidgen of top end match, at least it won't break again at that point.
