SLWS239A – JUNE 2013 – REVISED NOVEMBER 2015
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 V_PP (diff) in quadrature, and f_BB = 5.5 MHz, standard broadband output matching circuit,
unless otherwise noted.
