Description
The AV105-12 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 8 dB/V slope, with
input and output VSWR better than 1.4:1 over all states. Its attenu-
ation range at 1900 MHz is 31 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 25 pF DC blocking capacitors.
