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. 0.037 (0.95 mm) REF. 0.012 (0.30 mm) TYP. 0.014 (0.26 mm) 0.004 (0.10 mm) 5.0˚ ± 1˚ 0.006 (0.15 mm) 0.000 (0.00 mm) 5.0˚ ± 1˚ 0.122 (3.10 mm) 0.106 (2.70 mm) 0.022 (0.61 mm) 0.004 (0.10 mm) Electrical Specifications at 25°C (VS = 3 V) Parameter1 Insertion Loss (VC = 0 V) Maximum Attenuation (VC = 3 V)2 VSWR (I/O)3 Frequency 1.7–2.0 GHz 2.0–2.5 GHz 1.7–2.0 GHz 2.0–2.5 GHz 1.7–2.5 GHz Min.
