Patent ID: 7720115

Claim:
An rf pulse compression system comprising a power input for receiving power from an rf power source in the form of input pulses, a power output for delivering power to a load in the form of output pulses, a cavity resonator having a conductive resonator cavity wall and being symmetrical about at least two orthogonal axes, said cavity resonator further having a first coupling port in the resonator cavity wall at the intersection of the cavity wall with one of the resonator's symmetrical axes, and a second coupling port in the resonator's wall at an intersection of the wall with a symmetrical resonator axis that is 90 degrees from the axis location of said first coupling port, and a power dividing circuit for dividing pulse power from said power input between the first and second coupling ports of said cavity resonator for exciting two space orthogonal modes in said resonator, said power dividing circuit being connected to said power output and, upon reversal of the polarity of the input pulses after a resonator fill time, acting to combine power reflected from the cavity resonator with power produced from the energy stored in the orthogonal modes in said cavity resonator to produce compressed pulses for delivery to the power output.
