SLB Module – Dual RF MIMO transceiver
The SMT911 is an advanced, high-quality MIMO transceiver card, designed to cover all features of future high-speed MIMO radio systems. The SMT911 comprises two complete, fully configurable transceiver chains between two dual 12-bit digital I/Q interfaces and two dual-band 50 Ohm antenna ports for each channel.
Each transceiver chain is comprised of an integrated RF-frontend (band switch, T/R switch and power amplifier), up-/down converters with on chip PLLs and high performance analog-to-digital and digital-to-analog converters for the I/Q signals and additional analog-to-digital converters for RSSI conversion.
With a single on-board crystal or externally supplied common reference clock for the transceiver PLL’s, multiple SMT911 cards are easily combined to build an arbitrary size 2m x 2n MIMO system with coherent LO phase. All control signals, data bits and the SPI bus are routed through a 120-pin QSH data connector providing for flexible, application specific configuration and control during operation. The SMT911 is designed to fit on and connect directly to an FPGA base module like the Sundance SMT351T or SMT368. The provided demo SMT911 Firmware Control Module permits simple and unrestricted access to all control registers from a user friendly C-Language API.
