World-Band Transceiver ICs
AC ELECTRICAL CHARACTERISTICS — 802.11a Rx Mode (MAX2828/MAX2829)
(MAX2828/MAX2829 evaluation kits: V CC = +2.7V, f IN = 5.25GHz; receiver baseband I/Q outputs at 112mV RMS (-19dBV), f REFOSC =
40MHz, SHDN = RXENA = CS = high, RXHP = TXENA = SCLK = DIN = low, R BIAS = 11k ? , registers set to default settings and cor-
responding test mode, T A = +25 ° C, unless otherwise noted. Unmodulated single-tone RF input signal is used, unless otherwise indi-
cated.) (Tables 1, 2, 3)
