(0.41 mm) x 45˚ CHAMFER 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 attenuation 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. 0.197 (5.00 mm) 0.189 (4.80 mm) 0.010 (0.25 mm) 0.004 (0.10 mm) 0.158 (4.00 mm) 0.150 (3.80 mm) 0.010 (0.25 mm) 0.007 (0.17 mm) 8˚ MAX.
