Attenuators SMA Connector - Attenuators Flange Mounted - Integrated Design DC - 18 GHz Performance Tab, Slot, or Rod Contact for Microstrip use Interchangeable Transition Contact Pins Reduces Package Size and Weight This series of SMA flange mounted Connector-Attenuators are ideally suited for use on microstrip packages where size and weight are a consideration. By combining the Attenuator and the launching Connector, space and weight as well as cost savings is accomplished. The resistive film circuit is designed to improve reliability and lower mismatch losses by eliminating the need for separate coaxial components. The units exhibit low VSWR and are ruggedly constructed of stainless steel and are temperature stabilized for use in hostile environments.
