AV132-315
Description
The AV132-315 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 DCS and PCS
base station applications centered at 1837.5 MHz and
1960 MHz. The AV132-315 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 with 1.6 mA typical control current
at maximum attenuation. The AV132-315 is packaged in
a small outline LGA (Land Grid Array) surface mount
package with the internal elements affixed to an organic
BT substrate.
