Very-broadband IC module design technology

Baseband amplifier modules and analog multiplier circuits that demonstrate the highest performance ever reported have been designed and fabricated based on the new techniques.Hiqh-speed, very-broadband ICs for large capacity optical transmission systems have established a significant niche in the compound semiconductor market. This paper demonstrates new design technologies, which include a circuit technique that allows distributed circuit configurations to be employed extensively and a packaging and module design technique that utilizes electromagnetic field simulations.
