Description
The AV131-315 is a voltage controlled variable attenuator
from Skyworks' series of HIP3TM 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 AV131-315 employs a monolithic
quadrature hybrid and a pair of silicon PIN diodes to
achieve the specified low distortion performance. It
operates from 012 V at 1.6 mA typical control current at
maximum attenuation. The AV131-315 is packaged in a
small outline LGA (Land Grid Array) surface mount
package with the internal elements affixed to an organic
BT substrate.
