AV113-12
Description
The AV113-12 is a current controlled variable attenuator
from Alpha’s series of HIP3™ components. It is designed
to meet the wide dynamic range required in IMT-2000
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.
