The OSMT Interconnect
System is designed to meet
the growing demand for
surface mount RF connec-
tor technology. The OSMT
occupies less printed circuit
board (PCB) real estate
than conventional through
hole coaxial connectors. An
innovative microstrip mount-
ing pattern and plug recep-
tacle design ensure reliable
grounding and PCB reten-
tion characteristics. The
OSMT Interconnect System
also allows closer PCB
pitch/spacing, standing a
mere 4.2 [.165] (fully mated
height) off the board. A new
higher cable retention plug
receptacle has been added
to the OSMT product family.
This new design addresses
applications where force is
applied to the mated con-
nector interface as a result
of cable flexure between
boards or around other PCB
components.
The OSMT Interconnect
System consistently
achieves broad band elec-
trical performance through
6 GHz with a maximum
VSWR of 1.20:1 at 2 GHz
and 1.40:1 at 6 GHz. This
broad band performance
establishes a reliable inter-
face that can be utilized for
future system upgrades
without concerns for perfor-
mance degradation.
The OSMT plug receptacle
is designed for high volume
assembly using surface
mount technology and is
available in tape and reel
packaging for automated
pick and place board
assembly. The mating cable
jack is available terminated
to a specially designed
coax cable as either a
pigtail, jumper or standard
interseries connector
assembly.
Specially designed engage/
disengage tooling is avail-
able to ensure proper
alignment of the OSMT
interface during assembly.
The higher retention plug
receptacle can be hand
engaged as a result of a
unique lead-in chamfer
design which also aligns
the contacts prior to mating
to ensure mechanical
integrity. Interface durability
is rated at 100 mating
cycles.
The OSMT Interconnect
System is ideal for surface
mount applications in
telecommunictions, GPS,
consumer and automotive
electronics. The OSMT pro-
vides versatile RF solutions
for next generation intercon-
nect needs.
