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.
