This article proposes a methodology to ensure linear amplification of a load modulated balanced amplifier (LMBA) while keeping the power efficiency as high as possible over a frequency band ranging from 1.8 to 2.4 GHz and ...

With the increasing demands for higher data rate, wider signal bandwidth is required, and this imposes high sampling rate converters in the communications equipment. This paper provides and analyzes experimental results ...

This paper analyzes the computing resource management implications of SDR base stations implemented as SDR clouds. SDR clouds describe distributed antennas that connect to a data center for digital signal processing. ...

We describe the design and technical characteristics of a C-band SW accelerating structure of a 12 MeV race-track microtron, which is under construction at the Technical University of Catalonia, and its RF system with a ...

The waveforms being employed by fourthgeneration (4G) and candidate fifth-generation (5G) radio access and wireless backhaul technologies are based on modulation techniques that allow significantly increased spectral ...

This paper presents a study on the trade-off between the envelope’s slew-rate and the drain efficiency when slower envelopes are considered to dynamically supply the power amplifier (PA). This paper discusses a method ...

This paper focuses on the FPGA implementation of a slew-rate reduction (SR) shaping function for envelope tracking (ET) power amplifiers (PAs). The SR envelope has been proved effective to trade-off power efficiency and ...
