Wideband Software program Outlined Radio Board Reference Design

The module is designed for RF purposes, that includes programmability and a frequency vary of 70 MHz to six GHz, appropriate for 3G, 4G, and software-defined radios.

The AD-FMCOMMS3-EBZ is a complicated analogue module reference design from Analog Units (ADI) that highlights the capabilities of the AD9361, a high-performance RF transceiver appropriate for RF purposes similar to 3G and 4G base stations, take a look at tools, and software-defined radios. It options wideband flexibility and is programmable, making it splendid for numerous transceiver purposes. Integrating an RF entrance finish, a versatile mixed-signal baseband part and frequency synthesizers present a configurable digital interface to a processor or FPGA.

Working throughout a frequency vary of 70 MHz to six GHz, the AD9361 covers most licensed and unlicensed bands. It helps channel bandwidths starting from beneath 200 kHz to 56 MHz, which will be adjusted by modifying the pattern charge, digital filters, and decimation settings—all programmable immediately inside the chip.

The analysis board is designed for software program builders and system architects who require a platform that operates over a wider tuning vary than its predecessor. Whereas it meets the datasheet specs at 2.4 GHz, its efficiency throughout the total supported RF tuning vary can fluctuate. The board consists of efficiency information for your complete vary (70 MHz—6 GHz) to help in system testing and waveform growth.

This board primarily goals to facilitate system investigation and software program groups’ preliminary testing of assorted waveforms earlier than the finalization of customized {hardware}. The main focus right here is on sensible performance and statement of waveforms quite than optimizing the final 1dB or 1% EVM of efficiency. These looking for extra performance-oriented platforms could contemplate this reference design.

Distinguished from the AD-FMCOMMS2-EBZ’s use of the TCM1-63AX+ RF transformer from Mini-Circuits, the AD-FMCOMMS3-EBZ is healthier suited to purposes requiring a broader tuning vary. It’s informally referred to as the “Software program Engineers’” platform, highlighting its utility for intensive frequency protection and preliminary growth levels, versus the “RF Engineers’” platform supplied by the AD-FMCOMMS2-EBZ. Complete design sources and software program help for this board can be found on-line by way of the ADI web site.

The software program is tunable throughout a broad frequency vary from 70 MHz to six.0 GHz and helps channel bandwidths starting from lower than 200 kHz to 56 MHz. It options part and frequency synchronization on transmit and obtain paths, enabling excessive channel density. A single FMC connector powers the system and helps MIMO radio, attaining lower than 1 pattern synchronization on ADC and DAC. Moreover, it consists of complete design sources similar to schematics, structure, BOM, HDL, Linux drivers, and utility software program. The platform additionally helps add-on playing cards for spectrum-specific designs, together with energy amplifiers (PA) and low noise amplifiers (LNA).

ADI has examined this reference design. It comes with a invoice of supplies (BOM), schematics, meeting drawing, printed circuit board (PCB) structure, and extra.
