Abstract: ABSTRACT A METHOD AND A SYSTEM TO REALIZE SCALABLE WIDE BAND MULTI-CHANNEL TRANSCEIVER FOR FREQUENCY DOMAIN DUPLEXING (FDD)/TIME DOMAIN DUPLEXING (TDD) APPLICATION The present invention provides a wider bandwidth of receiver, ADC with higher sampling rate with baseband decimation and multirate filter processing. As generation of higher frequency in transmitter mode is not possible with sampling rate, multi Nyquist mode is used in the design to synthesize the signal. To improve the sensitivity and noise spectral density, analog synthesizers are used to improve the phase noise. The dependency on the analog chips for the phase shift and attenuation is reduced used the flexible IQ modulators.
