SDR system to meet the needs of the communications market

In the field of communications, the emergence of different and incompatible radio technologies has made the development of wireless communication products more and more difficult. Fortunately, the semiconductor industry has developed a radio frequency analog front end (AFE) supporting multi-function radios, which can accelerate the implementation of coverage. A wide range of wideband software-defined radio (SDR) systems to meet the rapidly changing needs of the communications market.

Communication upgrade new opportunity system design is no longer just IC
Due to the complex design of flexible broadband SDR, which involves a large amount of circuit design investment and the development and trade-off of algorithms, the industry has now developed a reference design using RF agile transceiver (Agile Transceiver). Xilinx FPGAs are used together. The AD-FMCOMMS2-EBZ Field Programmable Gate Array Mezzanine Card (FMC) from ADI is linked to the Xilinx main board via a single FMC linker to provide support for the AD9361 in the 2&TImes; 2 channel group The power and bandwidth required for the state setting (Figure 1). The board is fully customizable in software, does not require any hardware changes, and offers additional options for different Multiple Input Multiple Output (MIMO) configuration settings.

Figure 1 System developers can use the AD9361FMC board for development, debugging, evaluation, and tuning their SDR appliances with Xilinx FPGAs with minimal hardware configuration.

Reference designs include schematics, layout, overall bill of materials (BOM), hardware description language (HDL), Linux drivers, and application software, all of the key details needed to validate performance and perform rapid system prototyping. In addition to lower-level software and firmware, users can also use Simulink and MATlab support, which will enable the development and adjustment of program code for radio algorithms and performance.

Because this small, high-performance and flexible integrated circuit (IC) can replace a large number of discrete circuits, the need for these discrete designs will, of course, be considered to be terminated, but this is not the case. A discrete AFE design that is well-designed, carefully debugged, and properly tailored to the specific block, format, and bandwidth of the full range of SDRs, although it will have a larger base size, may exceed RF in that particular block The performance of agile transceivers. However, the real challenge is the extreme broadband nature of AFEs in SDR, which requires many spectrum-specific front ends like this, and each front end is a huge challenge for design and evaluation.

The components are real, and the FMC boards and tools are also true and have been incorporated into two existing SDR product designs. One is the USRP (Universal Software Radio Peripheral) from Ettus Research, and the other is the Maveriq MulTIchannel Reconfigurable RF Transceiver developed by Epiq SoluTIons.

Game Machine Wiring Harness

The wire harness simplifies the building of these larger components by integrating the wiring into a single unit, or several units, for [drop-in" installation. By binding the many wires, cables, and subassemblies into a harness, the OEM or installer only has one component to install. In addition, a wire harness allows the completed assembly to be better secured against the effects of abrasion and vibration, and by constricting the wires into a non-flexing bundle, usage of space is optimized.
