Abstract
This paper presents the design of a high performance and compactness coupler integrated with a 3D technology using BCB (Benzo-Cyclo-Butene) polymer. The main interests of the proposed technology are first the possibility to design multilayer passive devices to achieve high compactness and secondly to be able to monolithically integrate both passive and active circuits as the technological process is fully compatible with ICs. This technology was used to design coupler for which high compactness is reached by applying size reduction to the transmission lines. Electromagnetic simulations have been performed and show excellent performances in terms of amplitude and phase imbalance, isolation and return loss. Several versions of the coupler have been compared to emphasis such performances versus the reduction factor.

Abstract
This letter presents experimental results concerning a thin film bulk acoustic wave resonator realized on a thin GaN membrane and covered with a thin film of double walled carbon nanotube mixture. The quality factor was measured before and after the coating of the resonator with the nanotube thin film. The quality factor has increased more than ten times when the resonator was coated with nanotubes, due to their high elasticity modulus and low density, which confers a much higher acoustic impedance of the resonator electrodes and thus confines much better the longitudinal acoustic standing waves inside the resonator.

Abstract
This paper presents an analytical design methodology for 3D broadside couplers using new concept of compensation by coupled lines at both ends of a main coupler section. This compensation technique introduces a degree of freedom in the design which can enhance the compactness or the isolation of the coupler. Simulations have been performed and good agreement with the analytical analysis is observed. Two demonstrators have been then optimized and demonstrate a size reduction of 50% or a 10dB isolation improvement depending on the compensation scheme followed.
