Description
The AV101-12 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.
