DATA SHEET AV110-73, AV110-73LF: GaAs IC 30 dB Voltage Variable Attenuator Single Positive 3 V Control 1.7–2.5 GHz Applications ● Pin Out General-purpose telecommunication systems ● VS 4 ● 5 ● VC CBL 3 ● CBL GND Single positive 3 V control voltage 33 dB attenuation range @ 1.9 GHz Excellent linearity performance Negative transfer slope Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 °C per JEDEC J-STD-020 6 ● 2 Features 1 J1 J2 GND DC blocking capacitors (CBL) supplied externally. CBL = 25 pF for 1900 MHz operation. Description The AV110-73 GaAs IC FET voltage variable attenuator provides 33 dB attenuation range at 1900 MHz controlled by a single positive voltage. The VVA has a linear transfer curve of 12 dB/V slope, with input and output VSWR better than 2:1 over all states. It operates with supply voltage of 3 V and control voltage of 0 V to 3 V in a low-cost SOT-6 package. The RF ports require 25 pF DC blocking capacitors. NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.
