Dual, SiGe High-Linearity, 3000MHz to
4000MHz Downconversion Mixer with LO Buffer
+5.0V SUPPLY AC ELECTRICAL CHARACTERISTICS (continued)
(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 = 3200MHz to 3900MHz, f LO = 2800MHz to 3600MHz, f IF = 350MHz, f RF > f LO , T C = -40°C to +85°C. Typical val-
ues are at V CC = +5.0V, P RF = -5dBm, P LO = 0dBm, f RF = 3550MHz, f LO = 3200MHz, f IF = 350MHz, T C = +25°C, unless otherwise
noted.) (Note 8)
