SiGe High-Linearity, 2000MHz to 3000MHz
Downconversion Mixer with LO Buffer
+5.0V SUPPLY AC ELECTRICAL CHARACTERISTICS
(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 = 2300MHz to 2800MHz, f LO = 2000MHz to 2500MHz, f IF = 300MHz, 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 = 2500MHz, f LO = 2200MHz, f IF = 300MHz, T C = +25°C, all parameters are
guaranteed by design and characterization, unless otherwise noted.) (Note 6)
