Description
The AV103-12 GaAs IC FET voltage variable attenuator provides
35 dB attenuation range at 900 MHz controlled by a single positive
voltage. The VVA has a linear transfer curve of 9 dB/V slope, with
input and output VSWR better than 2.1:1 over all states. Its attenu-
ation range at 1900 MHz is 33 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 100 pF DC blocking capacitors.
NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
