The QMA push-pull replacement for SMA answers the need for a

QMA, push-pull latching connector that will mate with SMA threaded connectors,

the most widely used 50-Ohm RF coaxial connectors in the wireless industry. There

is a mechanical latch on the plug that mates with existing QMA jack design, but

will only release when the coupling nut is actuated. Mechanical testing with a

pull-force gauge consistently exceeded 80 pounds of axial retention.

BNC 75-Ohm connectors fulfill the current performance

challenges of the broadcast television/video industry. These passive connectors

and coaxial cabling encompass a significant portion of a typical broadcast

transmission line and allow for sizeable future bandwidth expansion without

connector hardware changes.

SMA field receptacle connectors are high performance

subminiature connectors for microwave frequencies. The threaded coupling ensures

uniform contact of the outer conductors, which enables the SMA to minimize

reflections and attenuation at higher frequencies, while providing a high

degree of mechanical strength and durability. Designed for high-performance and

low loss to 27 GHz, these connectors are available in various flange

configurations for ease of mounting on industry standard hermetic and

non-hermetic packages.

RF multi-port products provide users with a wide variety of

options and are ideal when package size, quality high-frequency response or

ganged mating is critical. The mating cable multi-port connectors can

accommodate a wide range of small standard and custom micro coaxial sizes up to

RG178. Additional features include:

  • Right angle, through-hole PCB and vertical SMT

    PCB versions

  • 50 and 75 Ohms
  • Latched and unlatched
  • Board-to-board and coaxial cable designs
  • Individual connectors and cable assemblies.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
