The UAA3587, the first Philips System-in-Package (SiP) solution to use a new silicon-based structure, is a complete RF transceiver for GSM, GPRS, and EDGE mobile phones. It uses innovative techniques to combine passive and active components in a single package, maximizing RF performance while significantly reducing external component count and overall design size. The SiP uses 35 fewer external RF components than the previous generation and enables a design area of less than 2.5 cm2 for the complete radio sub-system. Combined with the miniaturization of other components, the SiP offers increased RF performance while saving 30% more space than the previous "best-in-class" solution and 50% more than the industry average.
