Abstract
THE PROPOSED PROGRAM IS A FEASIBILITY STUDY AND SYSTEM DESIGN FOR AN INNOVATIVE POWER-AMPLIFIER SYSTEM FOR THE ADAPTIVE-JAMMER APPLICATION. THIS SYSTEM OPERATES OVER THE ENTIRE HF AND VHF RANGE (3 - 300 MHZ), PRODUCES SIGNALS WITH VARIOUS TYPES OF MODULATION, AND CAN CONCENTRATE ALL OF ITS POWER ON A SINGLE TARGET OR DIVIDE ITS POWER AMONG SEVERAL TARGETS. ITS POWER AMPLIFIERS CAN BE OPERATED IN CLASS AB TO PRODUCE A CLEAN OUTPUT SIGNAL OR IN CLASS D TO PRODUCE GREATER POWER WITH GREATER EFFICIENCY WHEN HIGHER LEVELS OF HARMONICS, IMD, AND SPURIOUS PRODUCTS ARE ALLOWABLE. THE SYSTEM IS BASED UPON WIDEBAND, MULTIMODE PA MODULES, HIGH-EFFICIENCY CLASS-S MODULATORS, HARMONIC CANCELLATION BY OUTPHASING, A BANK OF SWITCHED/TUNEABLE FILTERS, AND FEEDFORWARD ERROR CANCELLATION. CONTROL OF THE SYSTEM IS VESTED IN AN INTELLIGENT PROCESSOR.
