100 Ohm Differential Connector

Please suggest a type, part number, etc. of a 100Ohm differential connector with at least 1GHz bandwidth.

What connectors use LVDS or (differential) xECL digital links?

The differential connector I'm looking for should be about SMA sized...

What kind of connectors are used for Gbps Ethernet?

Thanks,
rfmw

Try samtec's connectors, they have 100 ohm differential connectors
