(V CC = +4.75V to +5.25V; GND = 0V; PSGND = GND; AGC = 1.3V; MOD = 0.8V; P RFIN = OFF, f LO = 1450.125MHz; P LO = -15dBm;
IOUT, QOUT = open; T A = 0°C to +70°C; unless otherwise noted.)
AC ELECTRICAL CHARACTERISTICS
(MAX2102 EV kit circuit (Figure 1); V CC = +5V; PSGND = open; MOD = GND; f RFIN = 2150MHz; P RFIN = -19dBm; f LO =
2150.125MHz; P LO = -15dBm driven single-ended into LO; AGC set via servo loop for V IOUT = V QOUT = 0.5Vp-p; IOUT, QOUT drive
AC-coupled 100 Ω loads; 2k Ω from PSOUT to GND; T A = +25°C; unless otherwise noted.)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
