Digital Step Attenuators

Analog Devices provides a range of broadband IC digital attenuators that come in low cost, leadless surface mount packages. Our digital attenuator family offers excellent attenuation and includes off chip ac ground capacitors for near dc operation, making it ideal for an extensive number of RF and IF applications.

Applications

• Cellular/3G infrastructure
• Microwave radio and VSAT
• Test equipment and sensors
• CATV/satellite set-top Boxes
• Data network equipment
• WiMAX, WiBN, and fixed wireless
• GSM, W-CDMA, and TD-SCDMA
• Fiber optics and broadband telecom
