Low-PIM Adapters for Wireless DAS

RFA-4195-01_200x162RF Industries manufactures a complete line of 4.1-9.5 (Mini) DIN to N and 7-16 DIN adapters and provides the most popular versions packaged in kit form, keeping these precision adapters organized and protected. Mini DINs are used in wireless infrastructure and DAS installations for their compact size and low PIM performance. Technicians encounter challenges to interface the Mini DINs with the more widely used N and 7-16 DIN connector interfaces.

Kits are available with the popular adapters in 6 and 7 pc variations. The right angle adapter features a radius internal design that provides constant 50 ohm impedance for optimum electrical performance to 7.5 GHz. Adapters with male interfaces have large hex coupling nuts for easy mating using a torque wrench. All adapters are manufactured with brass bodies and durable non-tarnish tri-metal (white bronze) plating with a PIM rating of less than or equal to -160dBc using 2 tones at 20 watts. www.rfindustries.com

QMA Connectors

RQA-5478QMA connectors available from RF Industries feature a snap lock connection as an alternative to the SMA connector with a threaded connection. The QMA connector, with a quick connect/disconnect feature along with electrical performance up to 6 GHz, is used in wireless infrastructure applications including DAS.

The RQA-5478 series adapter features a QMA female to N male interface that will allow connection of a QMA male terminated cable assemble to equipment with an N female connector. The adapter is manufactured with a machined brass body, plated in a durable tri-metal (white-bronze) finish. The contact is gold plated. The adapter is rated for low PIM performance of ≤ -155 dBc using 2 tones at 20 watts. www.rfindustries.com

Low PIM 4.1/9.5 (Mini) DIN Adapters

(mini) DINIn addition to eight variations of 4.1/9.5 (Mini) DIN to N type and 7/16 DIN adapters, RF Industries has added a 4.1/9.5 (Mini) DIN male to female right angle and straight adapters. The 4.1/9.5 (Mini) DIN is essentially a compact version of the 7-16 DIN with similar electrical performance. Applications include wireless infrastructure sites, indoor/outdoor DAS requiring low PIM performance. The right angle adapter features a radius internal design that provides constant 50 ohm impedance for optimum electrical performance to 7.5 GHz. Both adapters have large hex nuts on the male interface for easy mating with a torque wrench.  All adapters are manufactured with brass bodies in durable non-tarnish tri-metal (white bronze) plating with a PIM rating of less than or equal to -160dBc using two tones at 20 watts.

Coaxial Cable Assemblies for In-Building DAS

RF Industries offers coaxial cable assemblies with Times Microwave SPP-250-LLPL and TFT-402-LF plenum rated, low loss, low PIM, flexible cables that meet all requirements for an in-building DAS coaxial assembly. The SPP-250-LLPL is a small diameter corrugated cable. The TFT-402-LF is an extremely flexible, low minimum-bend radius cable. Both cables meet UL910 fire requirements and exhibit low loss and low PIM performance.

Cable assemblies are available in standard and custom lengths terminated with RF Industries brand or Times Microwave brand RF connectors. Connector terminations include 7-16 DIN male, 4.1-9.5 (Mini) DIN male, N male and SMA male. RF Industries applies high standards of manufacturing techniques and tooling with 100 percent final testing for electrical and PIM performance to assure every cable assembly meets the advertised specifications. www.rfindustries.com

N Connectors Simplified For Coax Cables Installation

RF Industries’ N-male connectors simplify the critical cable installation process by eliminating the need to trim the braid during cable preparation. The RFN-1006-49I features a solderless, captive pin while the RFN-1006-4I features a crimp pin. Combination hex/knurl coupling nuts allow for tightening by hand or wrench. White Bronze (tri-metal) plating eliminates tarnishing while providing improved electrical performance and reduced PIM. The devices exhibit an exceptional VSWR of less than 1.10 to 1 up to 3 Ghz and less than 1.20 to 1 up to 8 Ghz, which is achieved through an enhanced impedance matching design. Industry standard tooling can be used for cable preparation and crimp termination. Heat shrink and assembly instructions are included with each connector. VSWR charts are available. Connectors are compatible with high performance cables such as Times Microwave LMRR-400, CommScope CNTR-400, Belden 9913, and RF Industries RFI-CU400T. www.rfindustries.com
