Features
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, low-
distortion 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.
