RF Coax Connectors
Connector Selection
Connector Types
7-16 Series connectors are designed for medium to high power applications such as cellular base
stations, control components, antenna and broadcast. The 7-16 Series minimizes intermodulation
distortion by white bronze or silver plating the electrical path. Combined hex/knurl coupling nuts
allow for manual or torque tightening, further reducing distortion by providing a strong butt joint.
Lightning Protection devices have an integral surge arrestor capsule which is designed to protect
equipment from high current pulses. It is effective against very fast rise times as induced by electromag-
netic pulses from nuclear explosions (NEMP) and the slower pulses arising from lightning strikes (LEMP).
N Series threaded connectors have an air dielectric interface and are low cost. These connectors
operate to 11 GHz and are commonly used in cable-based local-area networks (LAN’s) medium
power transmitters, and base station antenna applications.
TNC connectors have an interface similar to BNC except for a threaded coupling nut. The tighter fit
provided by this screw-on connection improves interface control allowing connectors to operate up to
11 GHz. TNC connectors are excellent for mobile units where top-notch performance is required
under vibration.
BNC connectors offer easy engagement and disengagement using bayonet couplings and overlap-
ping dielectrics. They are most useful for frequently coupled and uncoupled RF connections with fre-
quencies below 4 GHz. BNC connectors find applications in flexible networks, instrumentation, and
computer peripheral interconnections.
F & G Series connectors offer enhanced performance beyond 1 GHz. Designed to meet the rigor-
ous requirements of Bellcore TA-NWT-001503 and SCTE specifications, the F & G series provides
high current carrying capabilities in both sealed and un-sealed configurations. Plugs, jacks and
adapters are available in threaded and push-on versions. These connectors meet the evolving
needs of the communications industry for increased reliability and performance.
SMA threaded connectors are widely used in microwave communications. Connectors operate to at
least 12.4 GHz on flexible coax cables, and up to 26.5 GHz on semi-rigid coax cables. Crimp-on
SMA connectors that operate to 26.5 GHz are available.
Blind Mate connectors operate to 22 GHz for OSP connectors, 28 GHz for OSSP connectors, and
40 GHz for SMP style connectors. These connectors offer easy slide-on connection and require less
alignment between the cable and the equipment than other connectors with comparable band width.
Blind Mate connectors are widely used as coaxial interconnects between plug-in modules and moth-
erboards when axial and radial misalignments are necessary.
SMB connectors feature a snap coupling for fast connection. A self centering outer spring and over-
lapping dielectric allows easy snap-on and excellent performance even in moderate vibration. The
SMB is smaller in size than the SMA and excellent where engineers are concerned about circuit
miniaturization. Typical application is inter- or intra-board connection of RF or digital signals.
Commercial 50 ohm versions operate to 4 GHz, and 75 ohm versions reach 2 GHz.
MCX connectors offer a high reliability, space saving sub-miniature coaxial cable to cable and cable
to board interconnection system. The MCX connectors impedance types are applicable up to 6 GHz.
Surface Mount (SMT) connectors. The RF solution to the communication and information age.
Tyco Electronics’ SSMT and SMT Quick Grip connectors are designed to meet the growing demand
for surface mount RF connector technology. These connectors operate up to 6 GHz utilizing cable
assembly design to terminate to SMT connectors. Surface mount connectors contribute to high
density packaging and high volume manufacturing requirements.
Multi Position connectors. These connector series, including the 1.0/2.3 (CECC 22230), 1.6/5.6
(CECC 22240), Subminiature D (DIN 41652 and CECC 75 301-082), and Tyco Electronics’ own
SIEMAX multi coax connector series offer the customer a broad choice of options where density and
performance are a major concern. The 1.0/2.3 series contacts are available in both 50 and 75 Ohm
versions and are designed for use to 10 GHz. The different types of coupling mechanisms, such as
screw on, slide-in and latching coupling provide for a variety of space-saving installations. The con-
nector series 1.6/5.6 has been modified to incorporate improved technical advantages. A 75 Ohm
design for use up to 8 GHz, it offers excellent screening effectiveness and is a most suitable compo-
nent for those applications where the transmission of high bit rates is required. In Subminiature D
type connectors these interfaces provide good electrical grounding and electromagnetic shielding in
a small package size. These plug connectors address the increasing demands related to EMC
(electromagnetic compatibility) and RFI (immunity to radiated noise), and are widely used as inter-
face connectors in office and data systems, telecommunications equipment, and in measurement
and control systems. Tyco Electronics’ SIEMAX connectors combine the benefits of surface mount
technology and modular design. This 75 Ohm connector series operates up to 2 GHz and offers a
compact grid pitch of 10mm. Its uses include multiplex and high-density systems, and Base Station
applications.
Miscellaneous connector types include multiple-circuit connectors that use coaxial contacts in a
pin-and-socket configuration, crimp-on ferrules that offer fast, reliable connections for attaching one or
more ground taps to shielded wire and braided shield terminations for connecting cable shields to pc
boards. Also available are network/premises interconnect products for Ethernet/IEEE 802.3 systems
and coaxial taps for simple, dependable connections from transceiver to LAN without cutting the cable.
