AC ELECTRICAL CHARACTERISTICS—Tx Mode
(MAX2831 EV kit: V CC_ = 2.8V, V CCPA = V CCTXPA = 3.3V, T A = +25°C, f RF = 2.439GHz , f LO = 2.437GHz. f REF = 40MHz, SHDN =
RXTX = CS = high, and SCLK = DIN = low, with power matching for the differential RF pins using the typical applications circuit.
100mV RMS sine and cosine signal (or 100mV RMS 54Mbps IEEE 802.11g I/Q signals wherever OFDM is mentioned) applied to base-
band I/Q inputs of transmitter (differential DC-coupled). Registers set to recommend settings and corresponding test mode, unless
otherwise noted. RF inputs/outputs specifications are referenced to device pins and do not include 1dB loss from EV kit PCB, balun,
and SMA connectors.) (Note 1)
