RF Coax Connectors
QMA Connectors
Snap-On SMA Series of
RF Connectors
Product Facts
■ Positive snap-on interface
facilitates assembly
■ Intermateable with
competitor product
■ Excellent RF performance to
6 GHz
■ Ideal for Communications
and Industrial Applications
Tyco Electronics’ next gen-
eration high performance
RF products QMA (Snap-On
SMA) connectors series
offers the same high quality
and performance currently
found in the standard
Tyco Electronics SMA series
but does not require the
coupling nut torque.
By integrating a snap-on
feature to the design,
denser packaging can be
achieved, and the overall
applied cost is dramatically
reduced. The QMA connec-
tor series is excellent for
communications as well as
industrial applications. The
QMA offering is designed
for 100 mating cycles, oper-
ates through 6 GHz, and is
completely intermateable
with competitive QMA offer-
ings. This new QMA prod-
uct is not intermateable with
standard SMA interfaces.
QMA connectors are avail-
able in a broad range of
standard configurations,
including PCB and panel
mount, flexible and semi-
rigid cable, and adapters.
Other options can be
reviewed as well, including
additional cable sizes, PCB
surface mounting, and tape
and reel packaging.
The QMA connector series
is a cost effective solution
for the challenging demands
of today’s commercial mar-
ketplace, with applications
including cellular base sta-
tion, handsets, and test and
measurement. Call your
local sales office or author-
ized distributor for additional
information or samples of
the QMA connector series.
Tyco Electronics is a lead-
ing supplier of RF and
Microwave connectors and
cable assemblies, and pro-
vides advanced technology
products from well known
and industry leading
brands, including AMP and
M/A-COM.
