CDMA IF VGAs and I/Q Demodulators
with VCO and Synthesizer
AC ELECTRICAL CHARACTERISTICS
(MAX2310/MAX2314 or MAX2312/MAX2316 EV kit, VCC = +2.75V, registers set to default power-up states, fIN = 210.88MHz for
CDMA, fIN = 85.88MHz for FM, fREF = 19.68MHz, synthesizer locked with passive 2nd-order lead-lag loop filter, SHDN = high, VGC
set for +35dB voltage gain, differential output load = 10kΩ, all power levels referred to 50Ω, TA = +25°C, unless otherwise noted.)
