| Abstract The need for integration of GSM, EDGE, and WCDMA in so-called WEDGE cellular handsets has disrupted the PIN diode and GaAs switch markets due to the performance, size, and cost requirements. This paper examines how UltraCMOS™ CMOS-on-Sapphire technology is monolithically solving the difficult performance challenges posed by this integration requirement, baselines it against competing GaAs solutions, and highlights the commercial success of the Technology. Last, this paper outlines the roadmap of continued scaling in device geometry, performance, and size. |
