MULTI BAND RECEIVER AND SIGNAL PROCESSING METHOD THEREOF

摘要

Present invention provides a multi band receiver for receiving and processing different frequency band signals which comprises: a direct sampling module for receiving and processing a low frequency band input signal from a first antenna; at least one single down conversion module for receiving and processing a high frequency band input signal from a second antenna; a combiner coupled to the direct sampling module and the at least one single down conversion module for combining the low frequency band input signal received from the direct sampling module and the high frequency band input signal received from the at least one single down conversion module; an Analog Digital Converter (ADC) coupled to the combiner for converting analog signal received from the combiner into digital signal.
