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.
