Description The AV108-59 GaAs IC FET voltage variable attenuator provides 35 dB attenuation range at 900 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. Its attenuation range at 1900 MHz is 25 dB. It operates with supply voltage of +3 V and control voltage of 0 V to +3 V in a low cost MSOP-8 package. The RF ports require 25 pF DC blocking capacitors.
