Description
The AV110-73 GaAs IC FET voltage variable attenuator provides 33 dB attenuation range at 1900 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. 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. Operating Characteristics at 25°C (VS = 3 V) 1. All measurements made in a 50 Ω system, unless otherwise specified. 2. Maximum attenuation includes insertion loss. 3. For worst case state.
