VCO Banda Larga Integrado para Receptor a Cinco Portas

Brito Filho, Francisco de Assis (Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia ElétricaAutomação e Sistemas; Engenharia de Computação; Telecomunicações, 2009-09-03)

This work presents an wideband ring VCO for cognitive radio five-port based receivers. A three-stage differential topology using transmission gate was adopted in order to maintain wide and linear tuning range and a low ...

J.; Wielinga, K.; Boland, W.; Graauw, M. W. M. de; Dishoeck, E. F. van; Jager, H.; Wild, W. (ESO, 2015)

Aims. We describe the design, construction, and characterization of the Band 9 heterodyne receivers (600-720 GHz) for the Atacama Large Millimeter/submillimeter Array (ALMA). First-light Band 9 data, obtained during ALMA ...

Integration of silicon-based MMIC technology for millimeter wave cryogenic receivers.

Ramírez Ortega, Wagner Esteban (Universidad de Concepción.Departamento de Ingeniería EléctricaDepartamento de Ingeniería Eléctrica., 2021)

This thesis work is framed in the area of astronomical instrumentation, specifically regarding the frequency range of millimeter wave. The demand for efficiency in the astronomical observations of low noise requires the ...
