TL;DR: In this article, three novel RF MEMS ohmic contact switches, each being designed for specific applications, were developed at Imperial College London, were presented. And the design, and measurements for all three unique solutions were briefly summarized.
Abstract: This paper reviews three novel RF MEMS ohmic contact switches, each being designed for specific applications. All three were developed at Imperial College London. The first is a packaged single-pole double throw (SPDT) version intended for space applications, operating from DC to 6 GHz; the second is a single-pole single throw (SPST) switch for high power applications in the 40 to 60 GHz band; and the third is a single- pole eight throw (SP8T) switch for signal routing applications, operating from DC to 20 GHz. The design, and measurements for all three unique solutions will be briefly summarized.

TL;DR: Hybrid integration techniques of planar and non-planar structures are discussed for low-cost and high-performance millimeter-wave integrated circuits (ICs) and systems and co-layered and aperture-coupling arrangements ofPlanar circuits and NRD-guide are presented.
Abstract: Hybrid integration techniques (HITs) of planar and non-planar structures are discussed for low-cost and high-performance millimeter-wave integrated circuits (ICs) and systems. Current status of this research topic is reviewed with emphasis on various integration/interconnect schemes of planar circuits and non-radiative dielectric (NRD) guides. Co-layered and aperture-coupling arrangements of planar circuits and NRD-guide are presented. Future trend is forecasted with emphasis on single substrate integration of planar and non-planar geometries. Substrate integrated circuits (SICs) are highlighted that can render the non-planar structures in planar form.

TL;DR: In this article, the relationship between sputter deposition conditions, AlN film structure, electromechanical coupling factor kt, and relevant electrical parameters of BAW devices are discussed, as well as their relationship with BAW resonators and filters.
Abstract: Thin film bulk acoustic wave (BAW) resonators and filters are well suited for mobile communication systems operating at high frequencies between 0.5 and 10 GHz. Piezoelectric thin film materials investigated for BAW devices within Philips include AlN thin films. The relationship between sputter deposition conditions, AlN film structure, electromechanical coupling factor kt, and relevant electrical parameters of BAW devices are discussed.

TL;DR: In this article, a comparative study on the suitability of using Hammerstein or Wiener models to identify the power amplifier (PA) nonlinear behavior considering memory effects is presented, taking into account the operational complexity regarding the identification process as well as their accuracy to follow the PA behavior.
Abstract: This paper presents a comparative study on the suitability of using Hammerstein or Wiener models to identify the power amplifier (PA) nonlinear behavior considering memory effects This comparative takes into account the operational complexity regarding the identification process as well as their accuracy to follow the PA behavior Both identified PA models will be used to estimate a Hammerstein based predistorter in order to see which model combination provides better linearization results In addition, two adaptive algorithms for predistorting both PA models are compared in terms of accuracy and converge speed
