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
SMA Connector - Attenuators
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 Connec-
tor, 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.
