Have a look for "antenna guard" from AVX. Maybe this is something for you

We have a fast digital connection (1.8Gbps) which is going =20
to the front panel of a unit. The connection is direct to an FPGA.
Such "outside world" Connectors are usually protected against =20
ESD using transorbs or zener diodes on the input lines. At =20
these gigabit speeds, zeners become capacitors and will distort the =
signal.
Can anyone recommend a suitable input protection scheme, or =20
any particular manufacturers products?
Many thanks,
