ELECTRICAL CHARACTERISTICS (continued)
Over recommended operating conditions; at power supply = 3.3 V, T_A = +25°C, V_CM = 0.25 V; LO Power = 0 dBm,
single-ended (LOP); GC set low, V_IN BB = 1.0 V_PP (diff) in quadrature, and f_BB = 5.5 MHz, standard broadband output
matching circuit, unless otherwise noted.
