( Typical Application Circuit, V CC = +4.75V to +5.25V, RF and LO ports are driven from 50
Ω sources, P
LO = -3dBm to +3dBm,
P RF = -5dBm, f RF = 700MHz to 1000MHz, f LO = 900MHz to 1200MHz, f IF = 200MHz, f RF < f LO , T C = -40°C to +85°C. Typical values
are at V CC = +5.0V, P RF = -5dBm, P LO = 0dBm, f RF =900MHz, f LO = 1100MHz, f IF = 200MHz, T C =+25°C, all parameters are guaran-
teed by design and characterization, unless otherwise noted.) (Note 6)
