This week’s Product Roundup highlights coaxial connectors for datacom applications from leading suppliers.

Coaxial Connectors for Datacom Applications

Amphenol RF coaxial connectorPEI-Genesis supplies Amphenol RF coaxial connectors used in high performance industries that require extremely reliable connections, such as automotive, broadband, broadcast, medical, wireless, military, aerospace, and industrial equipment. Common applications for Amphenol RF connectors include data transmission, broadband, wireless LAN/RFID, wireless infrastructure and instrumentation, or any radio frequency, microwave, and system application. Various frequency ranges can be addressed by Amphenol RF connectors and multiple connector types are available, including standard, miniature, sub-miniature and micro-miniature. Between-series adapters and special purpose Amphenol RF connectors are also available to meet specific requirements.


Samtec Bulls EyePowell supplies Samtec’s Bulls Eye® with high-density array designs and advanced cabling solutions that enable optimized performance, now to 70 GHz. Compression interface, small footprint, and high cycle count make Bulls Eye ideal for high-performance test applications.


Teledyne Reynolds 600 SeriesThe 600 Series from Teledyne is rated for use up to 10 kVDC and at altitudes of 70,000 feet (21.34 km) and above while exposed to temperatures as low as -55 °C and up to 125 °C. Capable of operating in the hard vacuum of deep space, these connectors are offered in shielded and non-shielded versions and use Teledyne’s patented Advanced Interface Sealing System.


Santron RF connectorsSan-tron’s high performance, 2.92 mm field-replaceable connectors for telecommunications, offered by CDM Electronics, are mode-free and deliver low-VSWR performance through 40 GHz. The 2.92 mm connectors are intermateable 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 made 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.


I-PEX CABLINE CA III-PEX CABLINE CA II is fully shielded with a mechanical lock. It offers high data-rate transfer (20 Gb/s/lane) — ideal for Thunderbolt 3 applications. Features include 0.4 mm pitch and a horizontal mating type micro-coaxial connector. ZenShield is fully shielded with multi-point grounds to prevent EMI leakage. The mechanical locking cover prevents incomplete mating and back-out/un-mating.


Cinch Connectivity Solutions introduced Johnson’s line of 1.0 mm (W) connectors and adaptersCinch Connectivity Solutions introduced Johnson’s line of 1.0 mm (W) connectors and adapters. This family of parts includes end launch and panel end launch screw-on style connectors, sparkplugs, and in-series adapters. They are designed to serve the 110 GHz (5G) testing requirements for R&D lab usage in the test and measurement industry, of vital importance to the telecom and datacom sectors, and semiconductor markets. They are designed for market leading operation DC to 110 GHz, 50-ohm impedance, with ruggedness and durability, offering excellent performance and repeatability, low VSWR, insertion loss, and return loss.


Connex SMA connectors supplied by Allied Electronics & AutomationConnex SMA connectors supplied by Allied Electronics & Automation are semi-precision, sub-miniature, high-frequency connectors which offer reliable broadband performance DC to 18 GHz, except as noted, with low reflection and constant 50-ohm impedance. All connectors listed, unless otherwise noted, are commercial grade construction, gold-plated brass bodies with 50 μ” gold contacts. All insulators are Teflon. All other parameters are equal to MIL standard construction. SMA connectors are frequently used in microwave systems, RF power amplifiers, RF isolators, and Wi-Fi antenna systems.


Harwin Datamate Mix-Tek connectorsHarwin now offers a new female contact option for its 4 mm-pitch Datamate Mix-Tek connectors, building on the program in which elements can be sourced separately. Like all Mix-Tek coax contacts, the M80-310 is designed for data carrying, with support for frequencies reaching up to 6 GHz. This latest contact can be fitted with a 1.19 mm/0.047” diameter semi-rigid coaxial cable. The 90° orientation means that it is optimized for situations with limited room above a cable-to-board connection. The M80-310 contacts are suitable for use with the complete range of different Mix-Tek high-reliability (Hi-Rel) housing types – from 2 to 12 position versions. These housings come with a variety of jackscrew styles to ensure mated connections capable of resisting up to 10G vibration and 100G shock. They are also fully compatible with all existing male coax contacts in the Mix-Tek portfolio, giving a 50-ohm impedance connection. With gold plated contacts and outer shell, these contacts can withstand a minimum of 500 mating cycles. These contacts will be stocked and available through Harwin’s global distribution network. They are well-suited to robots, field communications, industrial equipment, military/aerospace hardware, satellites/CubeSats, and other high-reliability applications.


The TR Multicoax high-speed coax connector from Amphenol Communication Solutions delivers superior signal integrity from multiple high-speed analog or digital channels. With a choice of 20GHz, 40GHz, or 70GHz configurations, users can upgrade their connectors according to bandwidth requirements on their application. 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 cannot be recovered and encouraging reuse across programs. The TR Multicoax offers an 80% space savings over subminiature push-ons (SMP).
