Description

The AV112-12 is a low distortion, PIN diode variable attenuator in a small SOIC-8 package.The design is based on Skyworks’ unique series of HIP3™ components. The AV112-12 consists of a monolithic quadrature hybrid and a matched pair of PIN diodes designed for low distortion attenuators. Parameter Min. Typ. Max.
