SBOS643A – APRIL 2014 – REVISED MAY 2014
Electrical Characteristics: V_S = +12 V (continued)
At T_A = 25°C, R_MATCH = 10.2 Ω, transformer turn ratio 1:1.4, R_L = 100-Ω differential at transformer output, full bias mode, and
active impedance circuit configuration, unless otherwise noted. Each port is tested independently.
