Abstract: A system and method is disclosed that provides a means for the high efficiency low distortion amplification of complex modulated radio frequency signals, such as but not limited to Single Side Band (SSB) signals. The innovative principle of the invention is based on the simultaneous amplitude and phase or angle modulation of Class "C" amplifier. Complex signals such as SSB signals can be described as a combination of amplitude and phase or angle modulation. By determining the amplitude and phase or angle components of the complex signal and using these to modulate a Class "C" amplifier, according to the manner prescribed in the invention, the objective of high efficiency low distortion is achieved. Previously, Class "B" amplifiers were required to amplify complex RF signals. The maximum efficiency of a Class "B" amplifier typically achieved in practice is about 40 percent compared to about 85 percent for Class "C" amplifiers. This increase in efficiency is very significant when applied to transmitters operating from batteries, solar cells, or other limited power sources in terms of size, weight, operating time and system cost.

Abstract: A spark gap switching device for high peak currents including a pair of main electrodes with protruding, opposing sub-electrodes, surrounded by high permeability cores typically of ferrite material. Small air gaps separate the sub-electrodes. The switch is activated by an over voltage or the like causing one of the sub-electrodes to breakover producing a flux time rate of change in the core. A voltage is induced in the non conducting sub-electrodes causing aligned pairs to rapidly increase in potential difference until one by one they all conduct.

Abstract: A resonant switching-type capacitive charging power conditioner circuit includes a trap switch assembly to prevent the energy initially delivered to the circuit by an electrical energy source, from returning to the source. Once trapped, all of the energy is transferred to a capacitive store over a number of cycles. The period for each cycle is a function of the state of charge of the capacitive store, and the period decreases for each successive cycle as the charge on the capacitive store increases to its final value. Switches are turned on and off in response to the absence of certain currents in the circuit, to match the decreasing period of each successive energy transfer cycle throughout the entire energy transfer process. This adaptive clocking prevents energy from returning to the energy source, and eliminates dead time for each cycle.

Abstract: The reduction of the grazing angle of electrons in an electron gun with a cathode emitting a beam of electrons which pass through a thin foil into a chamber is accomplished by geometrically tailored electron gun foil supports. One embodiment of the invention replaces the conventional rectangular shaped ribs with a set of triangular shaped ribs which produce a grazing angle A given by the equation ##EQU1## where T=the base width of the ribS=space between ribs at the baseH=height of the ribA=the angle the rib side makes with the incident electron which is perpendicular to the baseA=also the angle the electron scatters at from the rib surface.Another embodiment of the tailored foil supports entails the addition of triangular shaped caps to existing rectangular shaped ribs. The resultant reduction of the grazing angle of electrons improves the transmission efficiency of the electron gun and reduces the heat buildup on the supports and foil.

Abstract: It has been discovered that the transient voltage which develops on the outer sheath of a coaxial cable under pulse voltage excitation is a result of the inequality between the self inductance of the sheath and the mutual inductance between the sheath and the center conductor. The self inductance of the sheath is always less than the mutual inductance by a small amount because of the finite thickness of the sheath. By manipulating the design of the outer sheath, an equality between the sheath self inductance and the sheath to inner conductor mutual inductance can be achieved which results in a cancellation of the transient voltage on the sheath when the cable is pulsed.

Abstract: A device for charging PFLs (Pulse Forming Lines) on a time scale of a few nanoseconds. The device includes a source transmission line (STL) connected through a switch to a pulse forming transmission line. The source line is initially charged while the PFL is uncharged, and the switch is open. The impedance of the STL is larger than the impedance of the PFL. The impedance of the STL is also tapered in order to effect an energy transfer efficiency approaching 100% from the STL to the PFL. In operation when the switch is closed, energy flows from the source line to the PFL. As the energy and voltage build on the PFL, an output switch closes and delivers the energy of the PFL to the output transmission line section. The impedance of the output transmission line section is matched to the PFL impedance so that all of the energy in the PFL flows into the output section in the form of a pulse.
