DATA SHEET AV112-12, AV112-12LF: HIP3™ Variable Attenuator 1.7–2.0 GHz Features Connection Diagram Specified attenuation: 17.5–25 dB ● Total attenuation: 30 dB typical ● Low insertion loss: < 1.5 dB ● Low distortion: 40 dBm typical ● Low phase shift and delay ● Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 °C per JEDEC J-STD-020 ● RF Out RF In Description Control Current Control Current 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. AV112-12LF is packaged in a lead (Pb)-free, fully RoHS-compliant SOIC-8 package and is electrically identical to AV112-12. NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.
