Description

The AV102-12 is a current controlled variable attenuator

from Alpha’s series of HIP3™ components. It is designed

to meet the wide dynamic range required in spread

spectrum wireless base station applications. A monolithic

quadrature hybrid is teamed with a silicon PIN diode pair

in a plastic surface mount package reducing size and

assuring consistency from part to part.
