AC ELECTRICAL CHARACTERISTICS

(MAX2102 EV kit circuit (Figure 1); VCC = +5V; PSGND = open; MOD = GND; fRFIN = 2150MHz; PRFIN = -19dBm; fLO =

2150.125MHz; PLO = -15dBm driven single-ended into LO; AGC set via servo loop for VIOUT = VQOUT = 0.5Vp-p; IOUT, QOUT drive

AC-coupled 100

Ω loads; 2kΩ from PSOUT to GND; TA = +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.
