RF Evaluation and Development Kits, Boards play an important role in many technology areas with a focus on the RF methodology. In this article, we will discuss the application field and the working principle of ATA8520-EK2-E, a versatile evaluation and development board for cellular modems.

The ATA8520-EK2-E is a RF kit for testing and designing Cellular modems on Qualcomm and Intel platforms. This kit supports both 3G and 4G standards, including WCDMA, CDMA2000, LTE FDD, LTE TD-SCDMA, and TD-LTE. It supports 2G and provide the capability for core network and SIM card simulation.

In addition to its wide range of applications, the ATA8520-EK2-E board promises an easy and comprehensive development environment. It includes: Baseband development kit with sample code, integrated debugging environment, software support, and a variety of live measurement and live testing software. All of these features contribute to streamlined development work.

In terms of its working principle, ATA8520-EK2-E primarily functions by serving as a bridge between baseband software development and the network stack. In this way, the evaluation and development board executes commands from the development kit to transition the modem between sleep modes, make and receive calls, and initiate virtual test calls. The board also provides ports for RF connections, DSPs, and the baseband processor, as well as ports for UART and SDIO communications.

As for performance, the ATA8520-EK2-E features a full-track antenna that allows the modem to detect and monitor the signals of various base stations with higher accuracy. Its GPS (Global Positioning System) also gives reference signals with high accuracy allowing the modem to quickly register the network and establish a successful connection. In addition, the board also supports fast transmission and reception of data and voice in TD-SCDMA, TD-LTE, WCDMA, EV-DO, CDMA2000 and GPRS protocols.

The ATA8520-EK2-E is therefore a highly useful test and development kit for RF developers working on cellular modem projects. It features a wide range of applications, a comprehensive development environment, and high performance. This makes it an excellent choice to handle system validation and field testing for cellular modem designs.
