With the increasing availability of ultra-highspeed digital-to-analog converters (DACs), a direct digital synthesizer (DDS) can generate waveforms exceeding 1 GHz. Until now, however, no higheroutput DDSs have been able to provide the desired...
Although often overlooked, the package is an inseparable part of an RF/microwave semiconductor device, contributing to electrical performance and long-term reliability.
Given the need to cover multiple frequency bands in wireless handsets, the digital RF processor (DRP) offers many practical benefits to traditional receiver/transmitter approaches.
The latest generation of analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) provide performance in line with communications bandwidths and modulation requirements.
This efficient and flexible Volterra-based adaptive predistortion technique can be used to achieve high linearity in broadband RF power amplifiers.
