Description
The SKY12143-315 is a voltage controlled, variable attenuator from Skyworks series of HIP3™ components. It is specifically designed and specified for use as a wide dynamic range, low distortion attenuator for AMPS and GSM base station applications centered at 881.5 MHz and 942.5 MHz. The SKY12143-315 employs a monolithic quadrature hybrid and a pair of silicon PIN diodes to achieve the specified low-distortion performance. It operates from 0–12 V at 1.6 mA typical control current at maximum attenuation. The SKY12143-315 is packaged in a small outline LGA (Land Grid Array) surface mount package with the internal elements affixed to an organic BT substrate.
