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.
