Abstract

A fully integrated 5.8 GHz band transceiver LSI for electronic toll collection systems has been developed. The transceiver consists of LNA, down-converter, ASK detector, ASK modulator, voltage controlled oscillator, and AS-fractional-N PLL. Since internal RF matching circuitry for input terminal of LNA and output terminal of ASK modulator were also integrated, almost no external matching devices are necessary with VSWR<1.25. SBM for ASK modulator and VGA for LO amplitude control were adopted to avoid local leakage and to keep modulation linearity, result, obtained modulation index were over 95%. The infin-shape resonant coil was implemented for VCO to diminish magnetic coupling. Manufacturing process was SiGe BiCMOS process with 47 GHz cut-off frequency
