FUNCTION
Rx/Tx Gain-Control Digital Input Bit 2
Rx IF Ground. Make connections to ground vias as short as possible. Do not share
ground vias with any other branches.
Rx IF Supply Voltage. Bypass with a capacitor as close to the pin as possible. Do not
share the bypass-capacitor ground vias with any other branches.
Rx/Tx Gain-Control Digital Input Bit 3
Rx/Tx Gain-Control Digital Input Bit 4
Rx Downconverter Supply Voltage. Bypass with a capacitor as close to the pin as
possible. Do not share the bypass-capacitor ground vias with any other branches.
Rx/Tx Gain-Control Digital Input Bit 5
2.4GHz Single-Ended LNA Input. Requires AC-coupling and external matching network.
2.4GHz Tx PA Driver Differential Outputs. Requires AC-coupling and external matching
network (and balun) to the external PA input.
Exposed Paddle. Connect to the ground plane with multiple vias for proper operation and
heat dissipation.

The MAX2828/MAX2829 single-chip, RF transceiver ICs
are designed for WLAN applications. The MAX2828 is
designed for 5GHz 802.11a (OFDM), and the MAX2829
is designed for dual-band 2.4GHz 802.11b/g and 5GHz

802.11a. The ICs include all circuitry required to imple-
ment the RF transceiver function, fully integrating the
receive path, transmit path, VCO, frequency synthesiz-
er, and baseband/control interface.
Modes of Operation
The MAX2828/MAX2829 have seven primary modes of
operation: shutdown, SPI reset, standby, transmit,
receive, transmitter calibration, and receiver calibration
(see Table 5).
