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. In addition, an external grounding capacitor is required. 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 0.8–1.0 GHz 0.8–1.0 GHz 0.5–2.5 GHz Min.
