Amplificadores de potencia de alta eficiencia
(2015-01-12)The fast growth in modern wireless communication systems has set in motion a never-ending quest for greater capacity and higher data rates in radio access networks. These demands must be met within the existing radio base ... -
Consideraciones sobre el amplificador distribuido como amplificador de potencia
In this contribution, a short review of independent research activities on distributed power amplification is presented. An analysis of the intrinsic limitations of distributed power amplifiers serves as a guideline to ... -
DC-18 GHz MMIC tapered distributed power amplifier
Ng-Molina, Francisco Yak; Pérez-Parras, Sergio Luis
; Camacho-Peñalosa, Carlos; Martín-Guerrero, Teresa María (2014-07-22)
A DC-18 GHz MMIC tapered power distributed amplifier has been designed and simulated in GaAs technology. The amplifier has been designed according to the theory for power and efficiency maximization based on tapered drain ... -
Design Aspects of a Broadband Beam-Reconfigurable Leaky-Wave Antenna
Abdo-Sánchez, María Elena; Palacios, David; Frías, C.; Ng-Molina, Francisco Yak; Martín-Guerrero, Teresa María; Camacho-Peñalosa, Carlos[et al.] (IEEE Antennas and Propagation Society, 2016)
Design aspects of a novel beam-reconfigurable pla-nar series-fed array are addressed to achieve beam steering with frequency tunability over a relatively broad bandwidth. The design is possible thanks to the use of the ... -
Distributed Amplifiers in MMIC Technology based on Composite Right/Left-Handed Transmision Lines
Martín-Guerrero, Teresa María; Palombini, Diego; Mata-Contreras, Francisco Javier; Bentini, Andrea; Ng-Molina, Francisco Yak; Limiti, Ernesto; Camacho-Peñalosa, Carlos[et al.] (2013-11-13)
Abstract – Three MMIC distributed amplifiers based on Composite Right/Left-Handed Transmission Lines are presented in order to illustrate the actual performance of these devices, and the features that can be obtained with ... -
On the system performance of DFT-S-OFDM and CP-OFDM for 5G Uplink in mmWave band
(2021-09-20)Both conventional Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) and Discrete Fourier Transform Spread OFDM (DFT-S-OFDM) have been adopted for their use in the Physical Uplink Shared Channel (PUSCH) in ...
