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.
