Description
The AV109-73 GaAs IC FET voltage variable attenuator provides
35 dB attenuation range at 900 MHz controlled by a single posi-
tive 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. In addition, an external grounding capacitor
is required.
DC blocking capacitors (C
BL
) and RF bypass capacitors (C
BP
) supplied externally.
C
BL
= 25 pF for 900 MHz operation. C
