GSM900 and DCS1800/PCS1900
Dual-Band, Low-Noise Amplifiers
AC ELECTRICAL CHARACTERISTICS—MAX2651 (continued)
(MAX2651 EV kit, fIN = 945MHz (GSM band), fIN = 1850MHz (DCS band), PIN = -30dBm, input and output matching networks are
optimized for the frequency band of interest, all input/output ports terminated in 50Ω, VCC = +3V, TA = +25°C, unless otherwise noted.)
