Patent ID: 8090326

Claim:
A multi-frequency receiver, comprising: a multi-frequency combiner/divider; multiple receivers, wherein each frequency band of a plurality of frequency bands corresponds to ones of the multiple receivers and wherein receivers of a predetermined frequency band include a first group of receivers and a second group of receivers; one or more digital baseband interfaces; one or more first Radio Frequency (RF) interfaces configured to be connected to an antenna; and one or more second RF interfaces configured to be connected to an RF unit; wherein the multi-frequency combiner/divider is configured to distribute RF signals received from the antenna to the receivers of the predetermined frequency band based on the frequency bands; wherein the RF signals received from the antenna comprise multiple RF signals of different frequency bands; wherein the multi-frequency combiner/divider comprises multiple filters of the predetermined frequency band, the multiple filters configured to filter out RF signals of the predetermined frequency band from the RF signals received from the antenna; wherein the first group of receivers is configured to receive a first group of the RF signals of the predetermined frequency band and to send the first group of the RF signals to the RF unit via a second RF interface so that the RF unit converts the first group of the RF signals into first baseband digital signals and sends the first baseband digital signals to a baseband processing unit; and wherein the second group of receivers is configured to receive a second group of the RF signals of the predetermined frequency band, to convert the second group of the RF signals into second baseband digital signals, and to send the second baseband digital signals to the baseband processing unit via a digital baseband interface of the one or more digital baseband interfaces so that the first baseband digital signals and the second baseband digital signals, corresponding to the predetermined frequency band, are received by the baseband processing unit.
