For realizing a three-phase 400VAC/800VDC 10kW unity power factor PWM (VIENNA) rectifier system a novel Si/SiC multi-chip power semiconductor modules (IXYS VUM26B) facilitating switching frequencies up to 500kHz is employed. Direct water cooling of the modules base plates does significantly reduce the size of the cooling system. As the heat flow is directly from the power module into the water the cooling system can be realized using non-metal heat sink what does reduce common-mode EMI emissions. In this paper it is shown how the time behavior of the power module semiconductor junction temperatures over a mains period can be calculated with high accuracy by combining simple thermal equivalent circuits and stationary thermal simulations of the cooling system. Furthermore, the determination of the switching losses by circuit simulation based on experimental data is discussed and the power transistor and power diode junction temperatures are investigated for different operating points of the rectifier system.

In this paper, we present a novel ultra-compact embedded IC integration approach for System-On-Package (SOP) based solutions for RF and wireless communication applications. This concept is applied to the integration of a Ku band VCO module. The module fabrication is described and the impact of the packaging on the chip-set performances is discussed. The final thickness of the module is the thinnest reported till date and is about only 150 mum. The embedded VCO exhibits an oscillation frequency of 15.4 GHz, a phase noise of -99.2 dBc/Hz at a 1 MHz offset and maximum output power of 10.67 dBm. multi-layer interconnects built with modified MCM-D technology using advanced photosensitive epoxy Intervia(TM)8000 is described. We also present a detailed characterization and modeling of RF inductors. They exhibit a quality factor as high as 800@ 10GHz.

This paper presents, the design, realization and measured results of a highly integrated multi-chip-module (MCM) developed for X-band radar applications. The MCM is built up in a LTCC substrate. Embedded within the substrate is a bandpass stripline filter. The main functionality is realized by two multi-function MMIC. The MCM is an integral part of a future multi-channel AESA radar system.

This paper presents the design concept and experimental results about small size radio frequency (RF) module for 5 GHz wireless local area network (WLAN). Functions of the RF module include from base band input/output to antenna switch. The size is 20 mm/spl times/15 mm/spl times/3 mm and that is minimum size in modules with same functions as far as the authors get to know. For the purpose of small size and low cost, generally known technologies are used. They are multichipmodule on laminated-base dielectric substrate (MCM-L) technology, interconnection of each layer using build-up technology, flip chip technology and ball grid array (BGA) technology. Parts and ICs are on both sides of the RF module's substrate and are vertically connected in the substrate. In order to ensure electrical performance at 5 GHz frequency band in the high-density package, transmission line characteristics in the substrate and BGA characteristic are simulated by 3 dimensional (3D) electromagnetic (EM) software. The fabricated RF module is evaluated using the test set up for 5 GHz WLAN application and the result is shown.

We propose a novel multi-channel optical coupling technique called MOCA for the packaging of opto-electronic functional devices whose optical I/O ports are array optical waveguides. MOCA (multichannel optical coupling with an aspherical lens) uses only an aspherical lens to couple an optical waveguide array to an optical fibre array. Inspite of its simplicity configuration, MOCA provides efficint optical coupling for each optical I/O port and high performance for a module reliability. To confirm the performance of MOCA, we applied it to the packaging of an all-optical wavelength converter chip or SIPAS (Sagnac interferometer integrated with parallel amprifiers structure), which will be a key device in near future WDM networks. The fabricated module shows that the coupling loss of each I/O port is less than 3.5 dB and acts as an all optical wavelength converter for 10-Gb/s-RZ optical signal.

This paper presents a new test technique for embedded passives in multi-chipmodule (MCM) substrates. The technique uses an active circuit to test passive circuits in MCM substrates. The defect can be found with very high sensitivity due to the natural amplification of the op amp circuit used as a test apparatus. The technique is low-cost and can be applied to many different classes of passive filters that are embedded in MCM substrates.
