Publication Open Access Parametric study of pin surface used to suppress undesired modes in a packaged W-band microstrip receiver(IEEE, 2013) Rebollo Mugueta, Ainara; Maestrojuán Biurrun, Itziar; Larumbe Gonzalo, Belén; Gonzalo García, Ramón; Ederra Urzainqui, Íñigo; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta ElektronikoaA pin surface structure has been used in order to suppress undesired modes in a packaged W-band RF front-end receiver. A parametric analysis has been carried out in order to determine the optimum dimensions. Resonances suppression has been demonstrated.Publication Open Access Development of an auto-calibrated receiver in planar technology at millimetre-wave frequencies(2015) Rebollo Mugueta, Ainara; Ederra Urzainqui, Íñigo; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta ElektronikoaThis dissertation deals with the development of an auto-calibrated receiver at W-band for Passive Millimetre-Wave imaging applications. The proposed receiver has three main characteristics. Firstly, its differential configuration allows performing the internal calibration of the system. As opposed to total power receivers, this configuration reduces the effect of receiver instabilities. Secondly, it is entirely built in planar technology. As a consequence, a broadband planar antenna could be included in the same substrate resulting in a compact and light receiver. And finally, the W-band auto-calibrated receiver is based on a direct detection scheme which makes it simpler extending the number of receivers. Moreover, it uses commercially available low loss dielectric substrate and MMIC devices such as low noise amplifiers and detectors. This dissertation tackles all the required steps for the development of the W-band auto-calibrated receivers. Firstly, the theoretical analysis of the differential configuration was done highlighting its main advantages. Once this configuration was analyzed, the design of its W-band planar components, i.e. a quadrature hybrid coupler, WR10 waveguide to microstrip transition based on an E-plane probe and Vivaldi antenna fed by a slotline to microstrip transition, and the selection of the MMIC devices, i.e. low noise amplifier, reference load and detector, were carried out. Then, the analysis of the real configuration of the receiver was accomplished, identifying the effect of each component on its performance. After finishing the design, the proposed components were characterized. This process includes, as first step, the analysis of the dielectric constant and loss tangent of several substrates in order to determine their properties in the W-band. Afterwards, an inline WR10 waveguide to microstrip transition, required to characterize multiple planar devices at W-band frequencies with waveguide based measurement equipment was designed, manufactured and validated. This was the basic block used to characterize the manufactured components. Once the performance of these components was verified, the packaging metal block was designed and manufactured. It includes an innovative solution, based on a pin surface, in order to avoid the propagation of undesired modes, which can penalize the performance of the planar receiver. The experimental results prove the suppression of these cavity modes. Finally, the complete W-band auto-calibrated receiver was assembled and characterized in terms of input reflection coefficient, dynamic range, RF-DC response, effective bandwidth and equivalent noise temperature.
