Broadband RF Transceiver
DC ELECTRICAL CHARACTERISTICS (continued)
(MAX2837 evaluation kit: V CC_ = 2.7V to 3.6V, Rx set to the maximum gain; CS = high, RXHP = SCLK = DIN = low, RSSI and clock output
buffer are off, no signal at RF inputs, all RF inputs and outputs terminated into 50 Ω , receiver baseband outputs are open; 90mV RMS dif-
ferential I and Q signals applied to I, Q baseband inputs of transmitter in transmit mode, f REF = 40MHz, registers set to recommended
settings and corresponding test mode, T A = -40°C to +85°C, unless otherwise noted. Typical values are at V CC = 2.8V, f LO = 2.5GHz,
and T A = +25°C, unless otherwise noted.) (Note 1)

AC ELECTRICAL CHARACTERISTICS—Rx MODE
(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)
