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.
NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
