Typical Operating Characteristics (continued)
(MAX2116/MAX2118 EV kits, VCC = +4.75V to +5.25V, GC1 and GC2 set for maximum gain, VGND = 0, VIOUT = VQOUT = 800mVP-P
(MAX2116), loaded with 1kΩ VIOUT± = VQOUT± = 590mVP-P differential (DL = 0, MAX2118), VIOUT± = VQOUT± = 1VP-P differential (DL =
1, MAX2118), loaded with differential 2kΩ. Baseband LPF BW = 33MHz, fRFIN = 2175MHz. For default register values, see the Serial
Interface and Control Registers section. TA = 0°C to +85°C. Typical values are at VCC = +5V, TA = +25°C, unless otherwise noted.)
