Abstract
The present disclosure relates to an antenna filter unit (AFU) (280) communicatively coupled to a Radio Frequency (RF) Front End Module (RFEM) (250). The AFU (280) comprises a plurality of cavity filters and a Multiple-Input-Multiple-Output (MIMO) antenna unit to enable beam forming to multiple users.
Claims7
An antenna filter unit (AFU) (280), comprising:
- a plurality of cavity filters;
- and
- a Multiple-Input-Multiple-Output (MIMO) antenna unit coupled to the plurality of cavity filters, wherein the AFU (280) is blind-mated to a radio frequency front end module (RFEM) (250) through a pole between respective connectors on the AFU (280) and the RFEM (250), and the pole functions as a transmission line and a pole-connector interface forms part of the AFU (280) to route transmit and receive signals to the cavity filters, the AFU (280) and the RFEM (250) are configured on a high speed transceiver board (HSTB) (200) along with the transmission line that is connected between two connectors as the pole, wherein the HSTB (200) comprises a plurality of transceivers, and wherein digital signals received from Combined Central and Distributed Unit (CCDU) are converted into radio frequency (RF) signals and processed into analog signals using one or more converters to be transmitted to the RFEM (250).
A user equipment (UE) (302) communicatively coupled to a multiple input multiple output (MIMO) radio unit (100), the UE (302) comprising:
- one or more primary processors communicatively coupled to one or more processors of the MIMO radio unit (100) through a network (304), the one or more primary processors coupled with a memory, wherein said memory stores instructions which when executed by the one or more primary processors cause the UE (302) to:
- transmit one or more radio frequency (RF) control signals to the MIMO radio unit (100), wherein the MIMO radio unit (100) comprises an antenna filter unit (AFU) (280) having a plurality of cavity filters and a MIMO antenna unit, the AFU (280) is blind-mated to a radio frequency front end module (RFEM) (250) through a pole between respective connectors on the AFU (280) and the RFEM (250), and wherein the pole functions as a transmission line, and a pole-connector interface forms part of the AFU (280) to route transmit and receive signals to the cavity filters, wherein the AFU (280) and the RFEM (250) are configured on a high speed transceiver board (HSTB) (200) along with the transmission line that is connected between two connectors as a pole, wherein the HSTB (200) comprises a plurality of transceivers, and wherein digital signals received from Combined Central and Distributed Unit (CCDU) are converted into radio frequency (RF) signals and processed into analog signals using one or more converters to be transmitted to the RFEM (250).
A non-transitory computer readable medium comprising processor-executable instructions that cause a processor to:
- transmit one or more radio frequency (RF) control signals to a multiple input multiple output (MIMO) radio unit (100), wherein the MIMO radio unit (100) comprises an antenna filter unit (AFU) (280) having a plurality of cavity filters and a MIMO antenna unit, the AFU (280) is blind-mated to a radio frequency front end module (RFEM) (250) through a pole between respective connectors on the AFU (280) and the RFEM (250), and wherein the pole functions as a transmission line, and a pole-connector interface forms part of the AFU (280) to route transmit and receive signals to the cavity filters, wherein the AFU (280) and the RFEM (250) are configured on a high speed transceiver board (HSTB) (200) along with the transmission line that is connected between two connectors as a pole, wherein the HSTB (200) comprises a plurality of transceivers, and wherein digital signals received from Combined Central and Distributed Unit (CCDU) are converted into radio frequency (RF) signals and processed into analog signals using one or more converters to be transmitted to the RFEM (250).
