+5.0V SUPPLY AC ELECTRICAL CHARACTERISTICS
(DOWNCONVERTER OPERATION)
(Typical Application Circuit with tuning elements outlined in Table 1, V CC = +4.75V to +5.25V, RF and LO ports are driven from 50I
sources, P LO = -3dBm to +3dBm, P RF = 0dBm, f RF = 2300MHz to 2900MHz, f IF = 300MHz, f LO = 2000MHz to 2600MHz, f RF > f LO ,
T C = -40NC to +85NC. Typical values are for T C = +25NC, V CC = +5.0V, P RF = 0dBm, P LO = 0dBm, f RF = 2300MHz, f LO = 2300MHz,
f IF = 300MHz. All parameters are guaranteed by design and characterization, unless otherwise noted.) (Note 7)
