These connectors have an optimized contact pin and insulator design for UHD-data transmission and Swiss antraloy plating. They are fully compatible with conventional BNC chassis connectors and offer improved return loss values at high frequencies.
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 blindmate hardware attachment.
With a subminiature interface and a frequency range of DC to 40 GHz, Amphenol RF SMP connectors supplied by ICC (Interstate Connecting Components) are ideal for miniaturized high frequency coaxial modules. The full and limited detent systems provide respective levels of engagement and disengagement forces. This family of interconnects addresses all package design needs. In addition to microwave applications, the Amphenol RF SMP connector can be utilized as a highly shielded interconnect for high data rate applications. It can also be used in a board-to-board system using a floating bullet, which provides a link between mated pairs compensating for both radial and axial misalignment.
TR Multicoax series from Ardent Concepts, an Amphenol company, delivers superior signal integrity from multiple GHz+ channels. With a choice of 20 GHz, 40 GHz, or 70 GHz configurations, users can upgrade the connectors on their applications as bandwidth requirements increase. TR is the highest-density high-speed multicoax connector on the market. The interface is compression-mount, which drives lower total cost of testing by avoiding costly solder-down components that can’t be recovered, and encouraging reuse across programs.
The WP16RS Series (0.35mm Pitch Full Shield Board-to-board [FPC] Connector) from JAE is a full shield type that covers the entire circumference with a shell as an EMI countermeasure. It realizes good characteristics in the mmWave band by possessing a high frequency dedicated terminal (RF terminal) with a new structure. The signal terminal has a structure that supports a large current (1A per contact), and, by adopting a unique trumpet- type deep drawing shell and installing a metal guide inside the connector, makes the low profile board-to-board (FPC) connector robust and easy to align.
SMA Vertical Launch Coax Connectors from Cinch Connectivity are available for mid-board application in both microstrip and stripline versions, operating with high performance to 26.5 GHz. These connectors are screw-mount and solderless, allowing for quick and easy mounting and removal on PC boards. The side groove part enables microstrip or grounded coplanar waveguide (GCPW) designs. Applications include LAN routers, base stations, satellite communication equipment, phased array radar systems, airborne ground radar, MIMO, and active antennas.
Samtec continues to expand its coaxial cable assembly line by now offering .178″, 16 AWG cable assemblies (RF180 Series) featuring extremely low insertion loss and VSWR, with operating frequency to 18 GHz. This larger diameter, flexible cable is ideal for applications requiring lower loss over longer distances commonly found in the Mil/Aero market.

Measuring only 2 mm x 2 mm with a 0.92 mm mated height, the C.FL Series connector meets demanding requirements for miniaturization and high-performance. Delivering high signal integrity and low insertion loss, the C.FL Series features low reflection characteristics up to 30 GHz and has low voltage standing wave ratios (VSWR). Reduced phase difference between signals is improved by controlling the cable length accuracy. To simplify installation, the C.FL Series offers a wide self-alignment range of ±0.15 mm in the X and Y directions. A clear tactile click communicates proper mating.
The NEX10 from IMS Connector Systems is a new small coaxial connector system, offering low PIM and ruggedized design in a compact size to meet the upcoming space reduction requirements of small cells. As the telecommunications industry moves towards the small cell approach, the radio and antenna become smaller and require a small, high performing coaxial RF connector. The highlights of the new connector system are its excellent PIM stability of -166 dBc, flexibility of coupling mechanism (quick lock and screw), and ruggedized design in a compact size with flange height of 12.7 mm to suit the small cell radio and antenna size requirements.
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 a 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. Lightweight, semi-rigid and extra flexible versions for dynamic applications are also offered.
