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.

KEY FEATUREs
• Advanced, single-package RF transceiver for GSM/GPRS/EDGE
    - 30% smaller than previous best-in-class solutions
    - Total RF front-end < 2.5 cm2
• Eliminates 35 external components
    - Integrated Tx baluns, loop filters, decoupling capacitors
    - Integrated Fractional-N RF synthesizer with AFC control
    - Semi-integrated 26-MHz oscillator with integrated supply regulator
• Superior performance from optimal process technologies
    - 0.25µm QUBiC4 BiCMOS for RF performance
    - Passive integration for lower component count
    - Flip-chip assembly shortens interconnects, reduces parasitics
