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

DC ELECTRICAL CHARACTERISTICS (continued)

(MAX2830 EV kit, VCC_ = 2.7V to 3.6V, VCCPA = VCCTXPA = 2.7V to 4.2V, TA = -40°C to +85°C, Rx set to the maximum gain. CS =

high, RXHP = SCLK = DIN = ANTSEL = low, RSSI and clock output buffer are off, no signal at RF inputs, all RF inputs and outputs

terminated into 50Ω, receiver baseband outputs are open. 100mVRMS differential I and Q signals (54Mbps IEEE 802.11g OFDM)

applied to I/Q baseband inputs of transmitter in transmit mode, fREF = 40MHz, and registers set to recommended settings and corre-

sponding test mode, unless otherwise noted. Typical values are at VCC = 2.8V, VCCPA = 3.3V, and TA = +25°C, LO frequency =

2.437GHz, 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)

AC ELECTRICAL CHARACTERISTICS—Rx Mode

(MAX2830 EV kit, VCC_ = 2.8V, VCCPA = VCCTXPA = 3.3V, TA =+25°C, fRF = 2.439GHz, fLO = 2.437GHz; receiver baseband I/Q out-

puts at 112 mVRMS (-19dBV), fREF = 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)
