The integration of many different functions into one unit means that the component count has become very large. Since passive components form the majority of the devices mounted on the circuit board, there is considerable incentive to identify ways of reducing the number and/or size of these devices without compromising system performance. Interest is now focusing on the role that integrated passive devices (IPDs) can play in achieving some of these aims and a number of new approaches are emerging in this field. Integrated passive devices can provide a large number of passive components and functional blocks within a single device, reducing the overall complexity at the board level and improving the ease of assembly. In order to be effective, however, both the manufacturing and packaging technologies need to be selected to optimize performance, areal density and cost. Chip-scale packaging, combined with a thin film passive device technology and a large area format manufacturing capability offers a solution to these issues, as well as providing a package form factor compatible with existing surface mount assembly operation. This paper describes the thin film integrated passive technology and chip-scale packaging techniques which are being used to produce small outline, high performance integrated passive devices for use in a range of RF, wireless and digital applications.","PeriodicalId":226788,"journal":{"name":"Proceedings RAWCON 98. 1998 IEEE Radio and Wireless Conference (Cat.

Hence, the idea of extracting the poles in the complex plane so as to cover a wider response in frequency or time domain for the antenna circular array elements are calculated using rational function approximation in the complex frequency domain of double infinite series with unknown coefficients. The solution starts using electric field integral equation, application of the method of moments and extended boundary conditions. Then the poles are calculated using Prony's (1795) method for the input impedance and admittance of each antenna element. A newly calculated window type input impedance suffering from no singularities can be obtained. Impedances' or admittances' in the complex frequency plane are calculated by repeated application of the method of moments without the need of a newly computed matrix inversion. The method used in this paper is analogous to the formal method by the same author, which was done in the real frequency and without extracting the poles but rather using the inverse of the function describing the current, impedance or admittance. Also, the current distribution assumed was not a rational function in the complex frequency domain.","PeriodicalId":226788,"journal":{"name":"Proceedings RAWCON 98. 1998 IEEE Radio and Wireless Conference (Cat.
