Sub-nanosecond tuning of microwave resonators fabricated on ruddlesden–popper dielectric thin films
(Wiley, 2018-08-01)
Article
Accés restringit per política de l'editorialVoltage-tunable dielectric materials are widely used for microwave-frequency signal processing. Among tunable dielectric thin films, (SrTiO3)nSrO Ruddlesden–Popper (RP) superlattices have exceptionally low loss at high ... -
Independent digital predistortion parameters estimation using adaptive principal component analysis
(IEEE Microwave Theory and Techniques Society, 2018-01-01)
Article
Accés obertThis paper presents an estimation/adaptation method based on the adaptive principal component analysis (APCA) technique to guarantee the identification of the minimum necessary parameters of a digital predistorter. The ... -
Partial least squares identification of multi look-up table digital predistorters for concurrent dual-band envelope tracking power amplifiers
(IEEE Microwave Theory and Techniques Society, 2018-08-02)
Article
Accés obertThis paper presents a technique to estimate the coefficients of a multiple-look-up table (LUT) digital predistortion (DPD) architecture based on the partial least-squares (PLS) regression method. The proposed 3-D distributed ... -
Feed-forward technique to measure the reflection coefficient under CW high-power signals
(IEEE Microwave Theory and Techniques Society, 2018-10-01)
Article
Accés obertThis paper describes a measurement setup to obtain the reflection coefficient response over the frequency of a given device when this is subjected to a single-tone high-power (HP) signal. The proposed system is based on a ... -
Track detection in railway sidings based on MEMS gyroscope sensors
(Multidisciplinary Digital Publishing Institute (MDPI), 2012-11-23)
Article
Accés obertThe paper presents a two-step technique for real-time track detection in single-track railway sidings using low-cost MEMS gyroscopes. The objective is to reliably know the path the train has taken in a switch, diverted or ... -
Nonlinear effects of SiO2 layers in bulk acoustic wave resonators
(IEEE Microwave Theory and Techniques Society, 2017-12-29)
Article
Accés obertThis paper presents the development of a comprehensive distributed circuit model to account for the existing nonlinear effects in bulk acoustic wave (BAW) resonators. The comprehensiveness of the model and its distributed ... -
Teaching telecommunication standards: bridging the gap between theory and practice
(2017-05)

Waveguide filter modeling and simulation using mode-matching, fullwave network analysis and swarm optimization
(2017-02-01)
Article
Accés restringit per política de l'editorialThe paper presents the synthesis of forth-order waveguide bandpass filter, employing a symmetric configuration and leading to symmetric response with four poles and two transmission zeroes. For this synthesis we aimed to ... -
A multistate single-connection calibration for microwave microfluidics
(IEEE Microwave Theory and Techniques Society, 2017-10-12)
Article
Accés obertWith emerging medical, chemical, and biological applications of microwave-microfluidic devices, many researchers desire a fast and accurate calibration that can be achieved in a single connection. However, traditional ... -
Three-element filtering antenna array designed by the equivalent circuit approach
(2016-09-01)
Article
Accés obertThis paper introduces a design methodology of a third-order three-element patch array that has no filtering parts and yet behaves like a filtering antenna (filtenna). The design approach includes shaping the frequency ... -
Analysis of the optimum gain of a high-pass l-matching network for rectennas
(MDPI AG, 2017-07-25)
Article
Accés obertRectennas, which mainly consist of an antenna, matching network, and rectifier, are used to harvest radiofrequency energy in order to power tiny sensor nodes, e.g., the nodes of the Internet of Things. This paper demonstrates ... -
Tunable substrate integrated waveguide resonators
(2012-09-01)
Article
Accés obertThis paper presents a novel approach for providing SIW tunable resonators by means of placing an additional metalized via-hole on the waveguide cavity. The via-hole contains an open-loop slot on the top metallic wall. The ...
