DATA SHEET SKY12145-315: HIP3™ Variable Attenuator for UMTS Base Stations Features 23 dB attenuation range ● 1.5 dB insertion loss, 1.5:1 SWR www.DataSheet4U.com ● 0–12 V control voltage ● 43 dBm IP3 ● Small footprint LGA package ● Designed for UMTS base stations ● Lead (Pb)-free and RoHS-compliant ● Connection Diagram RF In/Out 10 pF Vcontrol 10 pF Control Voltage RF In/Out Vcontrol Description The SKY12145-315 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, lowdistortion attenuator for UMTS base station applications centered at 2140 MHz. The SKY12145-315 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 SKY12145-315 is packaged in a small outline LGA (Land Grid Array) surface mount package with the internal elements affixed to an organic BT substrate. 10 pF 10 pF NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.
