2.4GHz to 2.5GHz 802.11g/b RF Transceiver, PA, and Rx/Tx/Antenna Diversity Switch

Maxim Integrated 

2.4GHz to 2.5GHz 802.11g/b RF Transceiver, PA,

and Rx/Tx/Antenna Diversity Switch

AC ELECTRICAL CHARACTERISTICS—Tx Mode (continued)

(MAX2830 EV kit, VCC_ = 2.8V, VCCPA = VCCTXPA = 3.3V, TA = +25°C, fRF = 2.439GHz , fLO = 2.437GHz. fREF = 40MHz, SHDN =

RXTX = CS = ANTSEL = high, and SCLK = DIN = low, with power matching for the differential RF pins using the typical applications

circuit. 100mVRMS sine and cosine signal (or 100mVRMS 54Mbps IEEE 802.11g I/Q signals wherever OFDM is mentioned) applied to

baseband 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)
