System and design method of integrated macro gnodeb with carrier aggregation

A method (800) for operating a base station, the method (800) comprising:

• providing a base station having an integrated baseband and transceiver board (IBTB) with one or more network processors and one or more transceivers for processing Radio Frequency (RF) signals;
• receiving, at the one or more network processors, an external input direct current (DC) voltage from a backhaul and down converting the received input DC voltage using an isolated power supply to generate one or more control signals;
• processing, at an RF front end board (RFEB), the one or more control signals using a plurality of RF receive chains for signal reception, a plurality of RF transmit chains for signal transmission, and a plurality of RF observation chains that act as feedback paths from one or more power amplifiers of the RF transmit and receive chains to the one or more transceivers for linearization;
• and
• providing, by a cavity filter, a steeper roll-off outside operating band, the cavity filter operably interacts with one or more antennas via an interface.

A non-transitory computer-readable medium comprising processor-executable instructions that cause a processor to:

• provide a base station having an integrated baseband and transceiver board (IBTB) with one or more network processors and one or more transceivers for processing Radio Frequency (RF) signals;
• receive, at the one or more network processors, an external input direct current (DC) voltage from a backhaul and down convert the received input DC voltage using an isolated power supply to generate one or more control signals;
• process, at an RF front end board (RFEB), the one or more control signals using a plurality of RF receive chains for signal reception, a plurality of RF transmit chains for signal transmission, and a plurality of RF observation chains that act as feedback paths from one or more power amplifiers of the RF transmit and receive chains to the one or more transceivers for linearization;
• and
• provide, by a cavity filter, a steeper roll-off outside operating band, the cavity filter operably interacts with one or more antennas via an interface.
