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.
