400MHz to 2.5GHz, Low-Noise,
SiGe Downconverter Mixers
AC ELECTRICAL CHARACTERISTICS (continued)
(MAX2680/1/2 EV Kit, VCC = SHDN = +3.0V, TA = +25°C, unless otherwise noted. RFIN and IFOUT matched to 50Ω. PLO = -5dBm,
PRFIN = -25dBm.)

Note 1: Guaranteed by design and characterization.
Note 2: Operation outside of this specification is possible, but performance is not characterized and is not guaranteed.
Note 3: Two input tones at -25dBm per tone.
Note 4: This spurious response is caused by a higher-order mixing product (2x2). Specified RF frequency is applied and IF output
power is observed at the desired IF frequency (70MHz).
