Description
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.
