Abstract
A system for beamforming employing true time delay. The system includes a deserializer configured to receive a serial data stream and to convert the serial data stream into a plurality of parallel data streams, a zero-insertion block configured to insert zeroes into each of the parallel data streams, and a crossbar switch having a plurality of inputs and an equal number of outputs. The inputs are connected to the zero-insertion block, each of the outputs corresponding to one of the inputs. The crossbar switch is configured, in a first state, to connect each output to the corresponding input, and in a second state, to connect each output to an input different from the corresponding input, the set of outputs being a circular shift of the set of inputs.
