Voltage-Controlled Variable Attenuator: SKY12239-11
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.
The SKY12239-11 delivers monotonic attenuation performance over its entire control voltage range. This attenuator comprises four matched PIN diodes via an external control voltage signal. The control voltage range is from 1 to 5 V with a 2 mA typical control current at maximum attenuation. This device also does not require external components.
