AC ELECTRICAL CHARACTERISTICS (continued)
(MAX238_ EV kit, V CC = 2.7V, SHDN = high, f RF_IN = f LNA_IN = 2140MHz, f LO = 2330MHz (f IF = 190MHz). Mixer, LNA, and LO input
ports are driven with 50 Ω sources. R
BIAS = 24k Ω ±1%, P
LO = -10dBm (MAX2387/MAX2388), P LO = -4dBm (MAX2389), P RF =
-30dBm. Typical values are at V CC = +2.7V, T A = +25°C, unless otherwise noted.)
