Wireless Broadband RF Transceiver
AC ELECTRICAL CHARACTERISTICS—Rx MODE (continued)
(MAX2838 Evaluation Kit, V CC _ = 2.8V, T A = +25°C, f LO = 3.6GHz, f RF = 3.601GHz, receiver baseband I/Q outputs at 90mV RMS , f REF
= 40MHz, CS = ENABLE = RXTX = high, SCLK = DIN = low, channel bandwidth BW = 7MHz, with power matching for the RF inputs
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 that normally apply over the entire operating conditions, unless
otherwise indicated. Rx I/Q differential output load impedance = 10k Ω || 8pF.) (Note 1)
