The Radio420X FPGA mezzanine card (FMC)

is a powerful multimode SDR RF transceiver module designed around the state-of-the-art, multistandard, multiband Lime Microsystems LMS6002D RF transceiver IC, which supports broadband coverage, as well as TDD and FDD full duplex modes of operation.

The LMS6002D RF transceiver IC’s bandwidth

(1.5–28 MHz), selectable on-the-fly, makes it suitable for

a large number of narrowband and broadband applications with excellent channel selectivity. Combined with multiple references and synchronization modes, the Radio420X

is right at home in such applications as multimode software-defined radio (SDR), advanced telecommunications (MIMO systems, cognitive radios, WiMAX, white space,

Wi-Fi, GSM, WCDMA), and signal intelligence (SIGINT).

The Radio420X complies with VITA 57.1, a widely used standard in the digital signal processing industry, making

it easier for developers to integrate FPGAs into embedded system designs.

The Radio420X is also completely integrated to the

Nutaq μTCA Perseus AMCs, but it can as easily be used on any FMC carrier on the market. It is compatible with low-pin-count (one RF transceiver) and high-pin-count

(two RF transceivers) FMC interfaces.

HARDWARE ARCHITECTURE

The VITA 57.1 standard comes to the rescue of complex designs with its unprecedented mechanical and electrical flexibility. It offers standard specifications for small, mezzanine modules designed to adapt an FPGA-based carrier card to different I/O requirements.

FEATURES

The Radio420X features:

? 300 MHz–3.8 GHz RF frequency range

? 1.5–28 MHz programmable modulation bandwidth

? FMC LPC — one RF transceiver

? FMC HPC — two RF transceivers. See specifications for details.

? Maximum 20 dBm output power

? –103 dBm (low band) and –90 dBm (high band) input sensitivity

? 70 dB software-programmable RX/TX analog dynamic range

? Separate TX and RX antennas on the front panel

? Software-selectable RX filters bank (for standard wireless applications) and full-bandwidth option

? Selectable reference input — onboard, front panel, or FMC driven

? Reference output on front panel for synchronized multiboard/multichannel [MIMO] applications

? Equipped with an onboard, low-jitter reference clock, cross-point switch, and synchronization PLL

? Front panel I/O expander for external control (such as interfacing to an external TX PA)

? Shielded for noise immunity ANALOG RF PATHS (WITH SELECTABLE RX FILTER BANKS)

The Radio420X’s RX and TX analog paths are designed to offer the best versatility-to-performance ratio, addressing the high demands of multimode RF applications.

At the transmitter end, a software RF switch is used to select the low-band TX1 output or the high-band TX2 output of the LMS6002D. This switch is followed by a

6-bit, 4 GHz broadband amplifier where the gain can

be adjusted between –13.5 dB and 18 dB , on top of the integrated LMS6002D’s TX VGAs, yielding a maximum output power of 20 dBm.

At the receiver end, a similar 6-bit, 4 GHz broadband amplifier is present on top of the integrated LMS6002D’s RX VGAs. The amplifier is followed by a software-selectable switch that enables the LMS6002D’s low-band RX1 path or the high-band RX2 path. Each RX path has eight software-selectable filter banks. The table below

describes the filter banks on each path.

CLOCK MANAGEMENT FACILITY

The Radio420X’s clock management facility is designed around the CDCE62005 from T exas Instruments, which offers low-phase-noise clock distribution, a PLL core, dividers, dual VCOs, and a jitter cleaner feature. Combining the clock management facility to a

very-low-jitter, 4x4 crosspoint switch makes it possible to generate a variety of clocks necessary to the

Radio420X. The reference clock can be generated on

the FMC, through its carrier or through the front panel external reference input. The selected reference clock is available on the front-panel reference output

and is supplied to the FMC carrier.

A PPS signal can also be sent to the carrier’s FPGA

to dynamically adjust the Radio420X’s onboard VCXO through a programmable DAC — something especially useful when a GPS-disciplined clock is needed to drive reference clocks. For details about the GPS-disciplined FPGA core, contact Nutaq at info@https://www.wendangku.net/doc/da12368970.html,.

While the Radio420X natively supports 2x2 MIMO (Radio420M), feeding a common reference clock

to several units makes it possible to expand to 4x4

and beyond.

SISO AND 2X2 MIMO CONFIGURATIONS

The Radio420S (S for SISO) is an LPC FMC that complies with all the electrical and mechanical specifications of VITA 57.1, making it possible to use on any FMC-LPC compliant carrier on the market. On Nutaq’s Perseus AMC, it fits in a mid-size μTCA slot.

In 2x2 MIMO mode, a Radio420S and Radio420E—a Radio420S HPC with an LPC on top—are stacked to become the Radio420M (M for MIMO). The Radio420M complies with all the electrical specifications of VITA 57.1, but the height of the module fails to comply with the mechanical specifications. An additional 10 mm in height must therefore be allotted when using the Radio420M on an FMC HPC carrier other than Nutaq’s Perseus AMC. On the Perseus, it fits in a full-size μTCA slot.SPECIFICATIONS
