PRELIMINARY DATA SHEET AV104-12, AV104-12LF: GaAs IC 25 dB Voltage Variable Attenuator Single Positive Control 0.45–2.5 GHz Features ● ● ● 7 6 5 NEW GND VC CBL VS GND CBL 4 The AV104-12 GaAs IC FET voltage variable attenuator provides 25 dB attenuation range at 900 MHz controlled by a single positive voltage. The VVA has a linear transfer curve of 5 dB/V slope, with input and output VSWR better than 1.4:1 over all states. Its attenuation range at 1900 MHz is 22 dB. It operates with supply voltage of 5 V and control voltage of 0 V to 5 V in a low-cost SOIC-8 package. The RF ports require 25 pF DC blocking capacitors. 8 Description GND 3 J1 GND 2 ● Pin Out 1 ● Single positive 5 V control voltage 25 dB attenuation range @ 0.9 GHz High IP3 (20 dBm @ 0.9 GHz) Excellent linearity performance Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 °C per JEDEC J-STD-020 J2 DC blocking capacitors (CBL) supplied externally. CBL = 25 pF for operation >450 MHz. Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.
