( Typical Application Circuit (see Table 1). R1 = R4 = 681 I , R2 = R5 = 1.82k I , V CC = 4.75V to 5.25V, RF and LO ports are driven from
50 I sources, P LO = -6dBm to +3dBm, P RF = -5dBm, f RF = 1200MHz to 1700MHz, f LO = 1060MHz to 1560MHz, f IF = 140MHz, f RF > f LO ,
T C = -40 N C to +85 N C. Typical values are at V CC = +5.0V, P RF = -5dBm, P LO = 0dBm, f RF = 1450MHz, f LO = 1310MHz, f IF = 140MHz,
TC = +25 N C. All parameters are guaranteed by design and characterization, unless otherwise noted.) (Note 7)
