An adaptive transceiver architecture which reallocates communications resources in real time based on the amount of bandwidth being used in communications channels in the system. The transceiver receives communications signals from a plurality of communications beam spots. Each communications beam spot has a predefined bandwidth divided into non-overlapping subbands. The transceiver further comprises a plurality of front end signal conditioners for receiving communications signals from an equal plurality of communications beam spots. A predetermined number of the conditioned signals are then combined by an interconnect. The interconnect receives composite signals from the front end signal conditioners, and it combines at least first and second communications signals from first and second respective composite signals to form an output processing signal. The first and second communications signals are received by the receiver from first and second communications beam spots, respectively, and the first and second composite signals are output from the first and second corresponding front end signal conditioners.

A dual phased array payload (,) for use onboard a communications satellite is disclosed. The payload includes one or more phased array receive antennas (,) including numerous individual receiving elements distributed in a predetermined configuration. Each of the individual radiating elements is selectively adjustable in amplitude and phase to achieve scanning beams for receiving information transmitted from the ground in an uplink beam. The payload includes a packet switch (,) connected to the phased array receive antennas (,). The packet switch (,) includes a set of inputs and a set of outputs. The set of inputs are selectively connectable to the set of outputs. The payload (,) includes one or more phased array transmit antennas (,) connected to the packet switch (,). The phased array transmit antennas (,) include numerous individual radiating elements distributed in a predetermined configuration.
