Mini Coax+
connector system
The Mini Coax standard connector system is now
further enhanced with the
Mini Coax+.
This new
connector system has been originally developed
for 3rd generation telecom base stations.
Excellent transmission characteristics are realised
by the lowest connector losses and matched
impedances of all internal sections. The Mini
Coax+ connector therefore offers best transmission
characteristics for RF signals up to 4 GHz.
The modules are available in metric size 1.00 SU
(SU = System Unit = 25 mm) with 2 to 6 coaxial lines.
Mini Coax+ combines the advantages of both reflow
soldering principles SMC and SMT. SMC stands for
General information
'Pin in Hole' and therefore provides high mechanical
strength and endurance against dynamic and static
shearing forces. SMT stands for 'Pin on Pad' and
therefore provides highest RF performance of board
terminations (see Fig. 1). Both principles allow fully
automated assembly which promotes HARTING's
multi coax connector to a product which offers an all
in one solution:
automated board assembly
●
Robust design
●
Excellent RF performance
●
Fully
signal termination SMT

Based on available SPICE models for the
connector customers’ design-in can be supported
by HARTING's in house RF competence centre
with close co-operation. This guarantees
optimised signal transmission in the target
application. On this behalf our vision is to support
the customer from the design-in phase to a real
running application.
Mini Coax+ connectors are full mating compatible
to standard Mini Coax connectors and offer a
constant mating depth compared to product line
. Therefore a simultaneous use on one board
is possible in any mixed configuration (see Fig. 2).
