Low-Cost RF Up/Downconverter
with LNA and PA Driver
_____________________________Typical Operating Characteristics (continued)
(MAX2410 EV kit, VCC = 3.0V, VGC = 2.15V, RXEN = TXEN = low, fLO = 1.5GHz, PLO = -10dBm, fLNAIN = fPADRIN = fRXMXIN =
1.9GHz, PLNAIN = -32dBm, PPADRIN = PRXMXIN = -22dBm, fIFIN = 400MHz, PIFIN = -32dBm. All measurements performed in 50Ω
environment. TA = +25°C, unless otherwise noted. All impedance measurements made directly to pin (no matching network).)
