Quick-lock Connector — The QN Connector is a quick-connect version of the company's N series and provides performance up to 11 GHz. It offers low-loss RF performance, low RF leakage and high power handling capacity. The product features a snap-lock design suitable for hand assembly, which is said to save time and eliminate quality issues caused by torque variation. It is available in a panel-mount version with a smaller flange to fit more connectors in less space. Full 360° rotation of the plug is said to reduce stress on cable assemblies and eliminate the need to retighten hex nuts after installation. Huber + Suhner Inc., Essex Junction, Vt.

7/16 Connectors — These 7/16, 50 Ω Coaxial Connectors operate from DC to 8 GHz, and incorporate a co-molded, high-impact plastic flange over a brass body. The flange has been torque-tested for rotational durability and mounting retention. The connectors comply with the IEC and CECC22190 standards. Intermodulation properties typically measure -165 dBc. The products are available with any color flange and either silver or ternary alloy plating. Compel Electronics Inc., Ashland, Mass.
 |
Twist Connector — The EZ Twist F-type Coaxial Connector is said to reduce coaxial cable termination time with no tools or crimping required. The product reportedly also eliminates screw-on connections to outlets. The user pushes the connector onto an outlet to lock it in place, and pulls to remove. This feature is suitable for use in high-density installations where space is limited and conventional connectors are difficult to secure to outlets. Applications include commercial and residential coaxial applications. The Siemon Co., Watertown, Conn.
 |
Blind-mate Connectors — These Blind-mate Connectors (BMA to SSMP) are said to be mechanically robust. They are available in a range of sizes, from the size of an SMA to almost 70 percent smaller. The solutions provided by the products reportedly offer performance to 60 GHz and a range of sizes that make them suitable for systems requiring dense packaging. Tensolite, St. Augustine, Fla.
 |
Test Adapters — Quick-release Test Adapters incorporate push-on mating with an integrated locking mechanism that reportedly prevents mated surfaces from separating because of cable weight and handling. The locking outer contacts are heat-treated beryllium copper and the quick-release sleeves are passivated stainless steel for durability. Available series include N (male) to SMA (female), N (male) to N (female), TNC (male) to TNC (female), SMA (male) to SMA (female) and SSMA (male) to SSMA (female). Other series combinations can be manufactured. Connectronics Inc., Edinburgh, Ind.
