FUNCTION
Receiver Baseband Q-Channel Differential Outputs. In TX calibration mode, these pins are the LO leakage
and sideband detector outputs.
Receiver Baseband I-Channel Differential Outputs. In TX calibration mode, these pins are the LO leakage
and sideband detector outputs.

Detailed Description
The MAX2830 single-chip, low-power, direct conversion,
zero-IF transceiver is designed to support 802.11g/b
MAX2830
applications operating in the 2.4GHz to 2.5GHz band.
The fully integrated transceivers include a receive path,
transmit path, VCO, sigma-delta fractional-N synthesizer,
crystal oscillator, RSSI, PA power detector, temperature
sensor, Rx and Tx I/Q error-detection circuitry, baseband-
control interface, linear power amplifier, and an Rx/Tx
antenna diversity switch. The only additional components
required to implement a complete radio front-end solution
are a crystal, a pair of baluns, a BPF, and a small number
of passive components (RCs, no inductors required).
Rx/Tx and Antenna Diversity Switches
The MAX2830 integrates an Rx/Tx switch and an anten-
na diversity switch before the receiver and after the

power amplifier. See Figure 1 for a block diagram of the
switches. The receiver and transmitter enable pin
(RXTX) and the antenna selection pin (ANTSEL) deter-
mine which ports (ANT1 or ANT2) the receiver or trans-
mitter is connected to. See Table 1 for the Rx/Tx and
antenna diversity switches truth table. When RXTX = 0

(receive mode) and ANTSEL = 0, the switch provides a
low-insertion loss path (main) between the ANT1 port
(pins 4 and 5) and the receiver. When RXTX = 0
(receive mode) and ANTSEL = 1, the switch provides
