INDICATOR
Description
The A V106-12 GaAs IC FET voltage variable attenuator
provides 35 dB attenuation range at 900 MHz controlled
by a single positive v oltage.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 v oltage of +3 V and control
voltage of 0 V to +3 V in a low cost SOIC-8 pac kage.The
RF ports require 25 pF DC blocking capacitors.
