400MHz to 2.5GHz, Low-Noise,

SiGe Downconverter Mixers

AC Electrical Characteristics (continued)

(MAX2680/1/2 EV Kit, V

= SHDN = +3.0V, T = +25°C, unless otherwise noted. RFIN and IFOUT matched to 50Ω. P = -5dBm,

= -25dBm.)

RFIN

PARAMETER

LO Input VSWR

CONDITIONS

50Ω source impedance

MAX

UNITS

LO Leakage at IFOUT Port

LO Leakage at RFIN Port

IF/2 Spurious Response

= 1880MHz

dBm

-27

= 1915MHz, f = 1880MHz, f = 70MHz (Note 4)

-61

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).

Typical Operating Characteristics

(Typical Operating Circuit, V

= SHDN = +3.0V, P

= -25dBm, P = -5dBm, T = +25°C, unless otherwise noted.)
