Test and Measurement

With continued pressure for increased 3G coverage for smart phones, increased Internet connection for Wi-Fi and WiMAX, and the imminent introduction of 4G/LTE systems, design activity for digital communication RF components has never been greater. At the forefront of the design activity is the development of power amplifiers (PA).

The Universal Mobile Telecommunication System (UMTS), the successor to GSM, is steadily increasing its penetration of the world’s wireless communications markets, and is likely over time to become the primary standard used by not just the current 85% wireless carriers, but by virtually all of them. Its most promising emerging enhancement, Long-Term Evolution (LTE), has moved further along in the standards-setting process and on to the path of initial deployment.
