| PRELIMINARY DATA SHEET AV104-12: GaAs IC 25 dB Voltage Variable Attenuator Single Positive Control 0.45-2.5 GHz Features SOIC-8 Pin 8 0.050 (1.27 mm) BSC Single positive +5 V control voltage 25 dB attenuation range @ 0.9 GHz High IP3 (20 dBm @ 0.9 GHz) Excellent linearity performance Pin 1 Indicator 0.244 (6.20 mm) 0.228 (5.80 mm) Description 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.
