Abstract:We have developed a fully integrated 0.25um SiGe-BiCMOS transceiver with a power amplifier (PA), transmit / receive switch (T/R SW), orthogonal modulator / demodulator, received signal strength indicator (RSSI), and phase locked loop (PLL) for Dedicated Short Range Communications (DSRC) mobile terminals with Amplifier Shift Keying (ASK) and Pi/4shifted Quadrature Phase Shift Keying (Pi/4-QPSK) dual-mode modulation. Transmitter architecture is based on the sliding-IF topology using 4.6GHz VCO and a 1/4 divider.… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
