AC ELECTRICAL CHARACTERISTICS—Rx MODE (continued)
MAX2837 evaluation kit: V CC _ = 2.8V, f RF = 2.502GHz, f LO = 2.5GHz; receiver baseband I/Q outputs at 90mV RMS
(-21dBV), f REF = 40MHz, ENABLE = RXENABLE = CS = high, TXENABLE = 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, T A = +25°C, unless otherwise noted.
Lowpass filter is set to 10MHz RF channel BW. Unmodulated single-tone RF input signal is used, unless otherwise indicated.) (Note 1)
