Abstract: A communications circuit includes a first circuit block and a second circuit block. The first circuit block includes a first splitter, a first signal path coupled to a first output of the first splitter, a second signal path coupled to a second output of the first splitter, and a first switch configured to couple the second signal path to a third signal path or to couple a fourth signal path to the third signal path. The second circuit block includes a second splitter, a fifth signal path coupled to a first output of the second splitter, a sixth signal path coupled to a second output of the second splitter, and a second switch configured to couple the sixth signal path to the third signal path or to couple a seventh signal path to the third signal path. The third signal path extends between the first and second circuit blocks.

Abstract: A programmable radio frequency (RF) memory system includes a receiver designed to receive an RF pulse, a memory, a waveform transform module, and a transmitter. The memory stores a digitized version of the RF pulse. The waveform transform module is designed to determine one or more characteristics of the digitized version of the RF pulse, and based on the determined one or more characteristics, transform the digitized version of the RF pulse into a transformed signal. The transformed signal has at least one characteristic that is different than the one or more characteristics. The transmitter is designed to transmit an analog equivalent of the transformed signal. The analog equivalent of the transformed signal and the received RF pulse are coherent.
