Abstract

The gold-gold thermocompression process for power heterostructure bipolar transistor (HBT) flip chip has been modelled and simulated by finite element method. A model for plated gold creep has been determined on the basis of empirical data and model comparison. This model seems suited for gold-gold thermocompression process optimization.

Abstract

International audience; -Dans cet article, un circulateur auto-polarisé en technologie microruban fonctionnant en bande Q a été conçu, réalisé et caractérisé. Ce composant intègre un hexaferrite pré-orienté permettant de travailler à la rémanence, et ainsi, de s'affranchir de l'aimant permanent. A la différence des résultats publiés dans la littérature, l'utilisation d'hexaferrites de strontium substitués permet de travailler à une fréquence proche de 40 GHz sans impacter fortement les pertes d'insertion du dispositif. En mesure, il a été démontré que cette technologie permettait de réaliser des circulateurs ultracompacts, d'une masse inférieure à 3 mg, avec des performances électromagnétiques remarquables (pertes d'insertion = 0,45 dB à 35,8 GHz) à l'état de l'art de cette technologie.

Abstract

Email Print Request Permissions Save to Project This paper presents Micro-electro-mechanical relays for very fast switching applications. Prototype relays have been fabricated tested and demonstrated reconfiguration capabilities as fast as 70 ns with a 300 ns additional settling time once electrical contact is fully stabilized. Such switching speed has been previously demonstrated on capacitive RF-MEMS switches, but this is the first time that such a fast mechanical switching is reported on relays, i.e. ohmic contact switches. The ability to open or close a contact at such speed can lead to many applications such as ultra low power electromechanical computing, or harsh environment electronics.

Abstract

Broadband single pole four throw (SP4T) switches in coplanar (CPW) waveguide based on cantilever or clamped - clamped switches have been developed for use in space applications. All the devices are manufactured on high-resistive silicon using surface micro-machining technology. The SP4T switches provide very good performance in terms of insertion and return loss and isolation over a wide frequency band. These switches are intended to be used as building blocks for large order switching matrices for satellite applications. Full wave simulations and measured RF performances are shown to be in very good agreement, showing high performance for all SP4T typologies. Depending on the specific design, insertion loss between 0.5 and 1.25 dB, return loss between 20 dB and 26 dB and isolation between 35 dB and 50 dB has been obtained in the 0-6 GHz frequency band.

Abstract

Two different topologies of RF MEMS series ohmic switches (cantilever and clamped - clamped beams) in Coplanar Waveguide (CPW) configuration have been characterized by means of DC, environmental and RF measurements. The devices have been manufactured on High Resistivity (HR) Silicon substrates, as building blocks to be implemented in different Single-Pole 4-Throw (SP4T), Double-Pole Double-Throw (DPDT) configurations and then integrated in LTCC technology for the realization of Large Order Clos 3D networks.

Abstract

Wide-band gap (WBG) transistors give a real breakthrough for power devices compared to Silicon (Si) and Gallium Arsenide (GaAs) components. However, for space applications, the high power density of WBG transistors makes the thermal management critical and requires thermal investigations. Some packaging solutions dedicated to those power transistors are presented in this paper. The focus is made on diamond-based packaging with two topologies. In the first one, the die is soldered on a diamond carrier. In the second one, it is flip chip bonded on a diamond circuit. Thermal simulations, thermal cycling and electrical measurement results are given for both configurations.

Abstract

MEMS (Microelectromechanical Systems) technology plays a key role in the on-going miniaturization of electronic modules for automotive and consumer electronic products. In the microwave field, RF MEMS switches exhibit excellent RF properties as low power consumption, high linearity, low loss and high isolation compared to solid state electronic solutions. Based on these performances, we will present a status of the potentialities of RF-MEMS devices for application to future generation of space satellite payloads through some selected demonstrations achieved within Alcatel Space.

Abstract

The APOS (Advanced Power Subassemblies project addresses the devices (MMIC or discrete) used in the solid state power amplifiers (SSPA) that drive the transmit active antenna. These are key devices and their electrical and thermal performances have a major impact on both the satellite and the ground terminals. GaAs-based heterostructure bipolar transistor, due to their superior power/linearity performance, could be one of these enabling devices. This aspect will be addressed within the frame of this project through three main objectives : 1)To analyse the reliability of UMS HBT technology and demonstrate it meets the requirements of the commercial satellite markets. 2)To improve the power and thermal performances of HBT by developing a power flip- chip assembly technology using thermal bumps in the active area of the power device. 3)To benchmark the developed power HBT technology by using the power MMIC in a suitable active antenna module. This project consortium is formed by Alcatel Space, that will co-ordinate the project, United Monolithic Semiconductors (UMS), Thomson-CSF, Institute for Material Research at Limburg University Centrum (1MO-LUC), DESTIN and Institut d'Electronique et de Microelectronique du Nord (1EMN).
