MAX2839AS
The MAX2839AS direct conversion, zero-IF, RF transceiver
is designed specifically for 2.3GHz to 2.7GHz 802.16e
MIMO mobile WiMAX™ systems. The device incorpo-
rates one transmitter and two receivers, with > 40dB iso-
lation between each receiver. The MAX2839AS
completely integrates all circuitry required to implement
the RF transceiver function, providing RF to baseband
receive path, and baseband to RF transmit path, VCO,
frequency synthesizer, crystal oscillator, and base-
band/control interface. The device includes a fast-set-
tling sigma-delta RF synthesizer with smaller than 40Hz
frequency steps and a crystal oscillator that allows the
use of a low-cost crystal in place of a TCXO. The trans-
ceiver IC also integrates circuits for on-chip DC-offset
cancellation, I/Q error, and carrier leakage detection
circuits. An internal transmit to receive loopback mode
allows for receiver I/Q imbalance calibration. The local
oscillator I/Q quadrature phase error can be digitally
corrected in approximately 0.125° steps. Only an RF
bandpass filter (BPF), crystal, RF switch, PA, and a
small number of passive components are needed to
form a complete wireless broadband RF radio solution.
The MAX2839AS completely eliminates the need for an
external SAW filter by implementing on-chip program-
mable monolithic filters for both the receiver and trans-
mitter, for all 2GHz and 802.16e profiles and WiBro. The
baseband filters along with the Rx and Tx signal paths
are optimized to meet the stringent noise figure and lin-
earity specifications. The device supports up to 2048
FFT OFDM and implements programmable channel fil-
ters for 3.5MHz to 20MHz RF channel bandwidths. The
transceiver requires only 2µs Tx-Rx switching time. The
IC is available in a small wafer-level package (WLP)
measuring 5.16mm x 3.66mm x 0.5mm.
Applications
802.16e Mobile WiMAX Systems
Korean WiBro Systems
Proprietary Wireless Broadband Systems
802.11g or n WLAN with MRC or MIMO Down Link
