摘要： A power amplifier includes an input network, output stages, coupled in parallel and configured to output power optimally in corresponding power-ranges, the output stages coupled to the input network, an output impedance matching network, coupled to the output stages and not containing a switching element, and a bias-control network, coupled between the output impedance matching network, the input network, and the output stages. In some amplifiers the output impedance matching network does not contain a switching element corresponding to the output stage configured to output power in the highest range. In other amplifiers the bias-control network is configured to isolate output stages by providing a hard shut-off to transistors of the isolated output stages.

摘要： Described is a mobile radar system which provides both persistent surveillance and tracking of objects with adaptive measurement rates for both maneuvering and non-maneuvering objects. The mobile radar system includes a vehicle having mounted therein an active, electronically-steerable, phased array radar system movable between a stowed position and a deployed position and wherein the phased array radar system is operational in both the deployed and stored positions and also while the vehicle is either stationary or moving. Thus, the mobile radar system described herein provides for longer time on target and longer integration times, increased radar sensitivity and improved Doppler resolution and clutter rejection. This results in a highly mobile radar system appropriate for use in a battlefield environment and which supports single-integrated-air-picture metrics including but not limited to track purity, track completeness, and track continuity and thus improved radar performance in a battlefield.
