4-channel, MIMO, RF analog front end for the VHS-ADC and the VHS-DAC
Lyrtech's Quad Dual Band RF Transceiver is based on the MAX2829 single-chip RF transceiver IC, designed for OFDM 802.11 WLAN applications (while it can still be used with other multiplexing schemes). The transceiver covers the world-band frequency ranges of 2.400 GHz to 2.500 GHz and 4.900 GHz to 5.875 GHz, and offers a channel bandwidth of up to 40 MHz. The four onboard MAX2829 devices integrate all the necessary circuitry to implement RF transceiver functions, yielding fully integrated reception and transmission paths, VCO, frequency synthesizer, and baseband control serial interface. External power amplifiers, RF switches, RF band pass filters, and baluns are also present to supplement the MAX2829. The Quad Dual Band RF Transceiver comes in a standard 2U rack-mount with the RF, baseband, and control connections on the front panel.
Designed in partnership with Comlab, the Quad Dual Band RF Transceiver is a perfect match to the Lyrtech VHS-ADC and VHS-DAC advanced development platforms. These platforms provide analog-to-digital-to-analog multichannel conversion interfaces and digital signal processing capabilities. When they are combined to DSP–FPGA processing boards such as the SignalMaster Quad, the system becomes a complete and very-high-performance MIMO RF-to-advanced baseband development station solution.

Success stories
The Generic Hardware Demonstrator for MIMO Systems (GEDOMIS) hosts a real-time implementation of the IEEE 802.16e-2005 physical layer featuring a 2×2 MIMO configuration and a high 20 MHz bandwidth. The algorithms of the mobile WiMAX receiver were modeled with MATLAB, designed with custom VHDL and implemented in FPGA devices operating in real-time using Lyrtech’s VHS-ADC and SignalMaster Quad. The VHDL code was integrated to the target boards with Lyrtech's own BSDK. For details about GEDOMIS, click here.
