  1. 1. System-on-package solutions for multi-band RF front end

    Författare :Xinzhong Duo; Li-Rong Zheng; Kari Halonen; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; chip-package co-design; multi-band radio; system-on-package; Electronic structure; Elektronstruktur;

    Sammanfattning : Advances in microelectronics technology have enabled us to integrate a complex electronic system (such as a radio) on a single chip or in a single package module, known as system-on-chip (SoC) and system-on-package (SoP) paradigms. This brings not only new opportunities for system integration, but also challenges in design and implementation. LÄS MER
