GaAs Integrated Passive Technology at Freescale Semiconductor, Inc

摘要

Radio transmit modules continue to shrink in die size and cost, requiring novel approaches for integration of the numerous passive elements of the radio front-end. An Integrated Passive Device (IPD) technology has been established based on low cost mechanical grade LEC GaAs substrates, for application including impedance matching, filtering and switching. Low pass harmonic filters integrated with coupler for AMPS/GSM 824-915 MHz and PCS/DCS 1710-1910 MHz bands were designed and fabricated showing excellent performance.
