Abstract

See full text

An embodiment of the disclosed MIMO transceiver uses a single master clock to generate (i) the sampling-clock signals for the analog-to-digital and digital-to-analog converters and (ii) the multiple electrical local-oscillator signals that are used in various channels of the transceiver's analog down- and up-converters to translate signals between the corresponding intermediate-frequency and RF bands. The MIMO transceiver may employ a plurality of interconnected frequency dividers configured to variously divide the master-clock frequency to generate the sampling-clock signals and the multiple local-oscillator signals in a manner that causes these signals to have different respective frequencies. In embodiments designed for operating in the mmW band, the MIMO transceiver may also employ a frequency multiplier configured to multiply the master-clock frequency to generate an additional local-oscillator signal for translating signals between the mmW and RF bands.
