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.
