For the general public, software-defined radio (SDR) is a very "high-level" topic, and even for most electronic technology engineers, it is still a bit of a feeling of spring. In fact, this technology has been proposed for twenty or thirty years, limited by high cost and complex technical implementation, and has always been the exclusive favor of military applications. Well-known applications include the US Joint Tactical Radio System (JTRS) program.
At the Yiwei Media Industry Forum held recently, Zhang Xinming (Eagle), senior customer application manager of ADI Channel Management and Emerging Markets Division, delivered a keynote speech on "Innovative Applications of Software-Defined Radios". In the speech, Eagle took the AD936x series of RF transceivers that ADI began to launch in 2013 as an example. "The AD9361 and AD9364 have been in short supply since their launch, and our production and technical support have not kept up with the customer's progress." Define a hot market where radio technology is unknown.
Eagle's sharing of technical features of the AD936x includes an introduction to the ecosystem of ADI in collaboration with Xilinx and Avnet, as well as applications in the areas of unmanned aerial vehicles, LTE communications infrastructure and defense electronics. This lecture interprets the technology "gene" behind the software-defined radio boom from a professional and technical perspective, and changes the impression that the software-defined radio technology has always been "yangchun white snow" and "far away from us". The software-defined radio has actually Really come to our side.
Technical gene behind the fireTo understand the hot technical genes of the AD936x application, let's first meet the ADI "star" product line. The AD936x includes two dual-channel AD9361 and single-channel AD9364 two public versions and a number of market-specific, customer-specific models that are a family of high-performance, highly integrated RF transceivers with leading programmability and broadband capabilities. It is ideal for a wide range of transceiver applications. The device combines an RF front-end with flexible mixed-signal processing, integrates a frequency synthesizer, and provides a configurable digital interface to the processor, simplifying design and engineering lead-time. Operating over the frequency range of 70 MHz to 6.0 GHz, the devices cover most licensed and unlicensed bands and support channel bandwidths from 200 kHz to 56 MHz for a wide range of applications.
Because of this, Eagle believes that the AD936x application is popular because of its breakthrough chip design and advanced production test process, ensuring that highly integrated chips can meet the application requirements of software-defined radios, meeting the long-term requirements for RF bandwidth and integration. S180 is a must-have for many application/market OEMs, providing a unified reprogrammable radio platform for multiple radio solutions. The AD936x offers exceptional flexibility and configurability as well as support for field upgrades, but the integrated wideband transceiver solution was limited in performance and adjustable bandwidth before the advent of the AD936x, and many OEM manufacturers lacked a practical and cost-effective SDR design. Ability or resources. Discrete SDRs are complex and costly to design, and many customers lack effective hardware and RF signal chain design capabilities, resulting in time-to-market delays, so they need better integrated software-defined RF transceivers.
The integrated RF transceiver AD936x encapsulates the signal chain in a software configurable IC that includes mixers, frequency synthesizers for transmit and receive channels, analog filtering, data converters, and more. The transceiver is a universal, reprogrammable radio platform for a wide range of applications, enabling flexible, configurable, field-upgradable, low-risk reference designs that help customers streamline bills of materials for fast time to market and have smaller footprints and good Heat dissipation and excellent energy saving.
In terms of key features, the AD936x achieved a great breakthrough, which is the key to its great success in the market. The frequency range is 69% better than competing products and the channel bandwidth is increased by 111%, which is an "hard to resist" temptation for any enterprise that focuses on SDR technology applications. "Compared with competitors is the only one that can really be used. The similar products on the market, only to 3.8G, bandwidth of 28 megabytes, but do not support GSM 200KHz bandwidth, 1GHz noise figure is 3.5dB, 2GHz will not dare Marked, and we are 2dB and 3dB respectively," Eagle pointed out.
Compared to the AD936x, today's existing integrated broadband RF transceiver solutions are limited in performance and adjustable bandwidth. And engineers face increasingly complex design challenges where analog engineers need to understand FPGA and embedded design and system processing techniques, while digital engineers need to understand the basics of analog design, and hardware engineers need to use software modeling, all for any design engineer. They are extremely challenging. Engineers have been facing increasing market and technical challenges, and they need to provide reference designs that include software source code and drivers. ADI's timely introduction of the AD936x integrated design, high-performance technical indicators to meet these needs.
Easily implement “design-in†with a good ecosystem
This series is a traditional classic LED par light. As the most commonly used dyeing effect light on the stage, the par light is the most used one. There are not only styles suitable for indoor use, but also styles suitable for outdoor waterproofing. The brightness and effect are excellent. It is a very practical Stage Light. This series of lights is one of the most configured lights in the stage lights. It brings brightness and color transformation effects to the stage. It can make the stage effect better when matched with other series of effect lights.
