The 2.3 to 2.7-GHz MAX2839 single-chip WiMAX MIMO RF transceiver uses a dual-receiver architecture to mitigate RF channel fading, thereby increasing the SNR by as much as 10 dB compared to a single-receiver architecture. Both of the two receivers feature a 2.3-dB noise figure, −81-dBm sensitivity for a 64-QAM signal at 5-MHz channel bandwidth, and a 95-dB gain control range that is digitally controlled in 1-dB steps.
Factory calibrated to achieve better than −35dB EVM, −45dBc of sideband suppression, and carrier leakage of −40 dBc without dc-offset correction, the receivers simplify integration with the digital MAC/baseband IC. On the transmitter, the MAX2839 features a 62-dB gain control range, digitally controlled in 1-dB steps. Housed in a 56-pin TQFN package, the device operates from 2.7 to 3.6 V.
