Single-chip WiMAX MIMO RF transceiver from Maxim

Maxim has introduces the MAX2839AS, a single-chip, 2.3GHz to 2.7GHz, WiMAX MIMO RF transceiver offers ultra-small WiMAX modules for compact fixed and mobile applications.

The MAX2839AS uses dual-receiver architecture to mitigate RF channel fading 10dB, and the transceiver maximizes data throughput in nomadic and mobile WiMAX subscriber applications such as notebook computers, express/PC cards, USB dongles, smartphones, and in-home desktop CPE modems. The MAX2839AS is ideal for mobile WiMAX, Korean WiBro, and other OFDM-based wireless broadband systems.

The MAX2839AS incorporates two receivers that features low noise figure at 2.3dB, -81dBm sensitivity for a 64-QAM signal at a 5MHz channel bandwidth, and a 95dB gain control range that is digitally controlled in 1dB steps. Each device is factory calibrated to achieve better than -35dB EVM, -45dBc of sideband suppression, and carrier leakage of -40dBc.The transmitter features a 62dB gain control range, digitally controlled in 1dB steps. It delivers a 0dBm linear output with a 64-QAM signal, greater than -45dBc of sideband suppression, and more than -36dB EVM, while meeting a -70dBr spectral mask.

The key features of the MAX2839AS are,

Dual Receivers for MIMO, Single Transmitter
Complete RF Transceiver, PA Driver, and Crystal Oscillator
+2.7V to +3.6V Transceiver Supply
Low-power shutdown current

The suggested applications include 802.11g or n WLAN with MRC or MIMO down link, 802.16e mobile WiMAX systems, Korean WiBro systems, and wireless broadband systems.
