GaAs IC 35 dB Voltage Variable Attenuator
Single Positive 3 V Control 0.5–2.5 GHz
Preliminary
AV108-59
Features
s Single Positive +3 V Control Voltage
s 35 dB Attenuation Range @ 0.9 GHz
s Excellent Linearity Performance
Description
The AV108-59 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 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 voltage of +3 V and control
voltage of 0 V to +3 V in a low cost MSOP-8 package. The
RF ports require 25 pF DC blocking capacitors.
