RF Coax Connectors
Series MMCX (50 Ohm)
Micro miniature connectors
series MMCX (size 0.7/1.6;
CECC 22340) are primarily
intended for applications
where minimum dimensions
and space-saving design
are required. The connec-
tors are suitable for use up
to 6 GHz and are provided
with a reliable snap-on cou-
pling. Series MMCX con-
nectors are easy and fast to
assemble.
This connector family con-
tains straight and right
angled variants for cable or
solder connection and SMD
connectors for surface
mounting technology onto
PC boards.
