Midwest Microwave Attenuator kwiQMAte™ QMA Attenuator Emerson Network Power Connectivity Solutions offers the Midwest Microwave line of QMA attenuators featuring a pushon style SMA interface. This line of attenuators integrates the kwiQMAte™ interface into its industry leading high quality and performance line of microwave attenuators. These attenuators are offered as an alternative to standard SMA versions for new generation Telecom Base Stations and Mil-Aero applications with requirements for quick and secure low force mating in higher density configurations with space constraints. Replacing standard threaded SMA designs with the kwiQMAte™ snap-lock mechanism allow for increased packaging density as torque wrench clearance space is no longer required. Our unique snap-lock mating design provides excellent electrical performance and low VSWR. The kwiQMAte™ interface meets or exceeds the performance requirements of MIL-PRF-39012. These attenuators are 50 ohm devices which operate to 6.0 GHz. The attenuator bodies are constructed of brass with Tri-Alloy plating as a standard finish. All contacts are plated with 50 micro-inches of gold for excellent durability and performance in high frequency mating environments.
