TYPICAL PERFORMANCE CHARACTERISTICS

TGC MODE

Mode I = fSAMPLE = 40 MSPS, fIN = 5 MHz, LO band mode, RS = 50 Ω, RFB = ∞ (unterminated), LNA gain = 21.6 dB, LNA bias = midhigh,

PGA gain = 27 dB, VGAIN = (GAIN+) − (GAIN−) = 1.6 V, AAF LPF cutoff = fSAMPLE/3, HPF cutoff = LPF cutoff/12 (default), RF decimator

bypassed, and digital HPF bypassed, unless otherwise noted.
