Description
The AV133-315 is a voltage controlled variable attenuator
from Alpha’s 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 AV133-
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 AV133-315
is packaged in a small outline LGA (Land Grid Array)
surface mount package with the internal elements
affixed to an organic BT substrate.
