AC ELECTRICAL CHARACTERISTICS TABLE—Rx MODE (continued)
(MAX2839 Evaluation Kit, V CC_ = 2.8V, T A = +25°C, f RF = 2.4999GHz, f LO = 2.5GHz; baseband output signal frequency = 100kHz,
f REF = 40MHz, ENABLE = RXTX = CS = high, SCLK = DIN = low, with power matching for the differential RF pins using the typical
applications circuit and registers set to default settings and corresponding test mode, unless otherwise noted. Lowpass filter is set to
10MHz RF channel BW. Unmodulated single tone RF input signal is used with specifications which normally apply over the entire
operating conditions, unless otherwise indicated.) (Note 1)
