__________________________________________Typical Operating Characteristics
(MAX2411A EV kit, VCC = +3.0V, VGC = +2.15V, RXEN = TXEN = low, all measurements performed in 50Ω environment,
fLO = 1.5GHz, PLO = -10dBm, fLNAIN = fPADRIN = fRXMXIN = 1.9GHz, PLNAIN = -32dBm, PPADRIN = PRXMXIN = -22dBm,
fIF, IF = 400MHz, PIF = -32dBm (Note 1), all impedance measurements made directly to pin (no matching network), TA = +25°C,
unless otherwise noted.)
