Abstract: An active denial apparatus for use in non-lethal weaponry includes at least one focusing element configured to focus millimeter-wave energy along an axis of propagation. The at least one focusing element includes an astigmatic or dual axis focusing system configured to direct a focused beam that allows the active denial apparatus to accurately immobilize targets at both close and long range within acceptable limits of intensity.

Abstract: Systems, apparatus and methods that provide broadband predistortion linearizers including simple frequency desensitizers to maintain substantially the same predistortion in a relatively broad frequency band. For example, a broadband predistorter can include a nonlinear component to predistort the drive signal, and a simple frequency desensitizer to compensate the frequency dependence of the nonlinear component. In particular implementations, the nonlinear component can have a frequency dependent impedance that substantially changes across the broad operating bandwidth and the frequency desensitizer can include resistive and reactive elements, such as a resistor (R), an inductor (L), and a capacitor (C) in a resonator configuration, to compensate for the frequency-dependence of the nonlinear component in the broad operating bandwidth.

Abstract: The present invention pertains to a pre-distorter linearizer that incorporates a balanced-to-unbalanced transmission line transition as a phase shifter to feed the linear and non-linear arms of the linearizer with signals of substantially the same amplitude and with a frequency-independent and substantially 180-degree phase difference. Preferably the balanced-to-unbalanced transmission line transition is a slotline-to-microstrip transition. Several alternatives are shown to enhance the bandwidth performance of the linearizer. Using a slotline-to-microstrip transition as a phase shifter provides for a very physically compact and inexpensive design. Furthermore, the flexibility of the slotline-to-microstrip architecture allows the linearizer to be easily integrated into systems that use both solid-state and vacuum-tube amplifiers.

Abstract: A power combining array and method of increasing performance in a power combining array includes a waveguide enclosure having a plurality of slotline modules disposed therein. The slotline modules include input and output antennas that have varying physical characteristics to overcome differences in field intensity across the slotline module configuration and to account for phase changes. The varying physical characteristics include differences in longitudinal position, thickness, dielectric constant, and circuit element configurations.
