2.4GHz to 2.5GHz 802.11g/b RF Transceiver, PA,
and Rx/Tx/Antenna Diversity Switch
AC ELECTRICAL CHARACTERISTICS—Rx Mode (continued)
(MAX2830 EV kit, V CC_ = 2.8V, V CCPA = V CCTXPA = 3.3V, T A =+25°C, f RF = 2.439GHz, f LO = 2.437GHz; receiver baseband I/Q out-
puts at 112 mV RMS (-19dBV), f REF = 40MHz, SHDN = CS = high, RXTX = 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, unless otherwise noted.
Unmodulated single-tone RF input signal is used with specifications that normally apply over the entire operating conditions, unless
otherwise indicated. 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)
