The new SKY12239-11 is a voltage-controlled variable attenuator from Skyworks’ series of broadband, flat attenuation, high third order intercept point (IIP3) components. With operation over the 10 MHz to 1.5 GHz frequencies, this device is ideal for use as a wide dynamic range, low distortion attenuator in many applications, including those with automatic power leveling/gain control circuits in cellular base stations and point-to-point radio IF chains, and general wireless systems for military communications.
Skywork’s new series of voltage-controlled variable attenuators (VVAs) are optimized for use as low distortion, analog attenuators. The SKY12232-21, SKY12233-11, SKY12235-11 and SKY12236-11 cover operation ranges from 1.45 to 5.0 GHz, and have a range of control voltages from 0 to 5.0 V.
The SKY12361-350LF is a GaAs pHEMT four-bit broadband digital attenuator featuring an operating frequency of 0.1 to 3.7 GHz, and 15 dB attenuation with 1 dB least significant bit (LSB). This digital attenuator is ideal for a wide variety of cellular 3G and 4G infrastructure applications.
This two-bit, GaAs pHEMT digital attenuator is ideal for applications involving IF/RF systems and cellular/3G infrastructure, or any 100 Ω differential system that requires high attenuation accuracy, low insertion loss, and low intermodulation.
Skyworks' select digital attenuators are available for design into diverse wireless communications systems including cellular telephone base stations, land-mobile radio systems and point-to-point radio links. Featuring step size options as low as 0.25 dB, evaluation boards and samples are available from stock.
