RF and Coax Connector Product Roundup
Designed to simplify the connection process, Avnet’s new 6791 series wire-to-board connectors for coaxial cables enable simple termination with one press. Expanding the proven-reliable IDC (insulation displacement connector) from signal/power transmission to high frequency transmission field up to 6 Ghz, the IDC contact pierces the jacket and insulation of the cable and makes direct contact with the strands and conductor of the wire at the same time.
The MHF 7S from I-PEX offers excellent EMC performance with fully shielded design, ideal for 5G mmWave applications. Features include VSWR 1.5 max at 15 GHz in a small 2.0 x 2.0 mm footprint, a unique shielded design (ZenShield) that reduces unwanted EMI found in 5G mmWave applications, and an industry-first stripline terminated signal pin inside the receptacle ground contact. MHF 7S is halogen-free, REACH- and RoHS-compliant.
Axon’ Cable designs and manufactures RF coaxial assemblies and microwave coaxial assemblies with very low losses. For example, microwave coaxial assemblies working at a frequency of 50 GHz are characterized by optimized insertion losses at 2.45 dB/m and by shielding efficiency greater than 100 dB. Insulated with an FEP or PU jacket and terminated with coaxial connectors, the RF coaxial and microwave assemblies are easy to install. They are mainly used for measurement, radar, antennas, and surveillance systems. Axon’ Cable offers microwave coaxial cable assemblies designed to meet highly challenging environments. Mechanical protection can be added for a high level of crush resistance. Extra-flexible versions for high numbers of repetitive bends required for dynamic applications are also offered.

Smiths Interconnect’s MDCX, multipin coax connectors offer low VSWR of 1.25:1 (typ) up to 10 GHz (max mated pair), maximum overall diameter of 0.125″ fitted into low-profile micro-D housing, with constant 50 Ohm airline impedance. MDCX coaxial contacts are compact in size allowing multiple high density connections in a Micro-D style shell for applications where space and weight savings are important. No cumbersome spring mounts are required. These connectors are also available with locking post mechanisms or blind-mate hardware attachment.
CDM offers San-tron’s high performance 2.92 mm field replaceable RF connectors. They are mode free and deliver low VSWR performance through 40 GH. The 2.92 mm connectors are inter-mateable with SMA and 3.5 mm connectors. The pin of the 2.92 mm male connector is shorter than an SMA or 3.5 mm male pin so that the bodies of the male and female connectors engage before the pin and socket contacts. This mitigates wear from mating misalignment found with SMA or 3.5 mm connectors. The new 2.92 mm field replaceable connectors are available in 3/8- and 1/2-inch square, 2-hole .550” flange, and 2 hole .625” flange configurations for 0.009”, 0.012”, and 0.020” launch pin diameters. Other mounting options may be available upon request. They feature high performance gold-plated beryllium copper contacts, polyetherimide (PEI) capture bead, polychlorotrifluoroethylene (PCTFE) positioning bead and rugged stainless steel bodies. They fully comply with MIL-STD-348.

An RF connector, often referred to as a coax or coaxial connector, is an electrical connector designed to carry RF signals in a transmission line. RF connectors are typically used with coaxial cables and are designed to maintain the shielding that the coaxial design offers. RF connectors can also be mounted directly on a PCB to carry a signal to and from the tracks on the board, using a fastening mechanism such as thread, bayonet, or blind-mate, as seen on the 25-001-Q3-1-AH – N Type Solder Clamp Plug in white bronze from COAX Connectors. RF connectors also minimize the change in transmission line impedance at the point of connection in order to reduce signal reflection and power loss. By maintaining the shielding of the cable an RF connector will prevent external signals entering the circuit through electromagnetic and capacitive pickup. This allows the RF connector and cable to carry high frequency and high data-rate signals without interruption or degradation.

Rosenberger carries a wide range of RF coaxial connectors. High-frequency connectors are used to connect printed circuit boards, cables and devices, enabling very high frequencies to be transmitted. A consistent wave resistance (impedance) maintained in the transmission system is crucial. The diversity ranges from miniature to large and even heavy connectors – these must always function reliably no matter how tough the conditions. Not only are the connectors essential for enabling existing and future technologies, they must be able to adapt to ecological and economic conditions, withstand ever-increasing transmission rates, and continually satisfy demands for performance and reliability. Such requirements apply across all sectors, whether communication, medicine, industry, automotive, consumer goods, or other high-tech applications.
