MICROLAB/FXR Fixed Attenuators AA series General Purpose, Low Cost Pads DC to 1.0 GHz Wide Range of Standard Values Miniaturized Package Integral Matching Structures High Reliability 2 - 4 Watt Average Power Rating N, BNC or TNC Connectors Standard The Microlab/FXR AA series coaxial attenuators are for general-purpose applications in the DC to 1 GHz frequency range. Either the AB series or AH series is recommended for all applications requiring greater accuracy or wider frequency coverage. The AA series attenuators are constructed of resistive elements in a conventional -type circuit. They are bi-directional, exceptionally rugged, and negligibly affected by normal ambient temperature and humidity changes. AA series attenuators are available to order with special attenuation values, VSWR, power ratings, connector series, and connector polarities to meet your exact specifications.
