ConneCtorS
MDCX & MDHC
Smiths Connectors’ multipin MDCX and
MDHC coax connectors have a constant
50 ohm airline impedance interface and
are 30% smaller than our SCX coaxial
connectors. Each coax contact has a
maximum overall diameter of 0.125" fitted
into a low-profile metalized housing.
MDCX and MDHC coaxial contacts
are compact in size allowing multiple
high density connections in a Micro-D
style shell for applications where space
and weight savings are important. No
cumbersome spring mounts are required.
These connectors are also available with
locking post mechanisms or blind-mate
hardware attachment.
Insert arrangements are available in 2,
4, 6, 8 and 10 way coax assemblies as
well as mixed signal, power, coax and
high speed twinax contacts for hybrid
arrangements.
MDHC high frequency coaxial contacts
are a drop in replacement to Smiths
Connectors’ MDCX RF contacts with an
increased frequency range from 10 GHz
to 40 GHz.
►
MDCX VSWR of 1.25:1 (typ) up to
10 GHz (max mated pair).
►
MDHC VSWR of 1.3:1 (typ) up to
30GHz (max mated pair).
►
MDHC VSWR of 1.5:1 (typ) up to
40GHz (max mated pair).
