AC ELECTRICAL CHARACTERISTICS—Rx Mode (continued)

(MAX2831 EV kit: VCC_ = 2.8V, VCCPA = VCCTXPA = 3.3V, TA =+25°C, fRF = 2.439GHz, fLO = 2.437GHz; receiver baseband I/Q out-

puts at 112 mVRMS (-19dBV), fREF = 40MHz, SHDN = CS = high, RXTX = SCLK = DIN = low, with power matching for the differential

RF pins using the typical applications and registers set to default settings and corresponding test mode, unless otherwise noted.

Unmodulated single-tone RF input signal is used with specifications which normally apply over the entire operating conditions, unless

otherwise indicated. RF inputs/outputs specifications are referenced to device pins and do not include 1dB loss from EV kit PCB,

balun, and SMA connectors.) (Note 1)
