Midwest Microwave Attenuator kwiQMAte QMA Attenuator Emerson Network Power Connectivity Solutions offers the Midwest Microwave line of QMA attenuators featuring a push- Key Features & Benefits on style SMA interface. This line of attenuators integrates the Excellent VSWR and attenuation accuracy kwiQMAte interface into its industry leading high quality and Compact, high quality design Ideal for high density packaging applications performance line of microwave attenuators. These attenuators High performance kwiQMAte interface are offered as an alternative to standard SMA versions for new Offered from stock in 1, 2, 3, 6 & 10 dB generation Telecom Base Stations and Mil-Aero applications values with other dB values(1-30dB) with requirements for quick and secure low force mating in available upon request 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 Materials Rugged Brass Tri-Alloy Construction longer required. BeCu spring construction 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. All dimensions are inches Technical Drawing Technical Specifications Performance Impedance: 50 Ohms Frequency Range: 0-6 GHz Attenuation Values: 1, 2, 3, 6, and 10 dB Nominal* Attenuation Accuracy: +/-0.5 VSWR Max: 1.30 Average Input Power: 2 W Max +25C, Derated Linearly to 0.5W at +125C Temperature range -55 to +125 C Shock MIL-STD-202, Method 213, Condition I Thermal Shock MIL-STD-202, Method 107, Condition B ( except +85C high temperature) Vibration Sinusoidal MIL-STD-202, Method 204, Condition D Emerson Network Power Connectivity Solutions Emerson Network Power and the Emerson Midwest Microwave Network Power logo are trademarks and 299 Johnson Ave. Whilst due care has been taken to ensure the contents of this data sheet are service marks of Emerson Electric Co.
