CAD for Low-Cost and High-Volume Production There have been extraordinary recent advances in computer-aided design (CAD) of RF/microwave circuits, particularly in full-wave electromagnetic (EM) simulations. They have been implemented both in commercial and specific in-house software and are being applied to microwave filter simulation, modeling, design, and validation [1]. The developments in this area are certainly stimulated by increasing computer power. In the past decade, computer speed and memory have doubled about every 2 years [2] | Microstrip Filters for RF Microwave Applications. Jia-Sheng Hong M. J.

They have been implemented both in commercial and specific in-house software and are being applied to microwave filter simulation modeling design and validation 1 . The developments in this area are certainly stimulated by increasing computer power. In the past decade computer speed and memory have doubled about every 2 years 2 . If we accept the idea that this trend can continue it is not hard to imagine how this increased capability will be used. Another driving force for the developments is the requirement of CAD for lowcost and high-volume production 3-4 . In general besides the investment for tooling the cost of filter production is mainly affected by materials and labor. Microstrip filters using conventional printed circuit boards are of low cost in themselves. Using better materials such as superconductors can give better performance of filters but is normally more expensive. This may then be evaluated by a cost-effective factor in terms of the performance. Labor costs include those for design fabrication testing and tuning. Here the weights for the design and tuning can be reduced greatly by using CAD. For instance in addition to controlling fabrication processes to tune or not to tune is also much the question of design accuracy and tuning can be very expensive and time costuming for mass production. CAD can provide more accurate design with less design iterations leading to first-pass or tuneless filters. This not only reduces the labor intensiveness and so the cost but also shortens the time from design to production. The latter can be crucial for wining a market in which there
