HIP3™ Variable Attenuator 2.10–2.30 GHz AV113-12 Features ■ Low Loss 1.4 dB Typical SOI ■ Attenuation 18 dB Typical C-8 SOI C-8 ■ Good VSWR <1.5:1 Typical ■ Small SOIC-8 Package ■ For IMT-2000 Applications 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.
