Abstract: A solid-state amplifier architecture is disclosed. In some embodiments, the disclosed architecture may include first and second channel chipsets configured to amplify either the entire instantaneous frequency band of a radio frequency (RF) input signal or, respectively, sub-bands thereof, which may be divided proportionally between the two chipsets. In some cases, the chipsets may be configured to amplify frequencies in excess of the entire K-band and Ka-band frequencies simultaneously. In some cases, the architecture may be configured to address a signal received, for instance, from an electronic warfare (EW) system to a log amplifier stage configured to output a signal to the EW system, in response to which the EW system may generate a RF signal for amplification by the architecture for transmission. To facilitate heat dissipation, the architecture may be coupled, in part or in whole, with a thermally conductive carrier, optionally with an intervening diamond heat spreader layer.

Abstract: An ultra-wideband high-power solid-state transmitter for electronic warfare applications which includes a plurality of wideband Gallium-Nitride (GaN) semiconductor monolithic-microwave integrated circuits (MMICs), a spatial power combiner to sum the aggregate contribution of the MMICs, a wide bandwidth small form factor driver amplifier module to supply the required gain in the transmitter, and a thermal management system.

Abstract: A radio frequency energy radar system having a transmitting antenna system for transmitting and directing CW radio frequency energy toward a target. A receiving antenna system, adjacent to the transmitting antenna system, receives portions of the transmitted CW radio frequency energy reflected by the target. The receiving antenna system including a plurality of antenna elements disposed along a path and arranged to provide an antenna pattern having a main lobe antenna pattern directed toward the target and adjacent side lobe antenna pattern. A septum is positioned between the transmitting antenna and the receiving antenna, for shielding unwanted portions of the transmitted CW radio frequency energy from passing directly from the transmitting antenna to the antenna elements of the receiving antenna The shielding means terminates along an edge positioned in a region forward of the antenna elements.
