Abstract :
An extended resonance technique for designing power amplifiers is investigated. This technique provides a planar power-combining structure whose primary distinction from conventional structures is that it does not require quarter-wave or multiple quarter-wave spacing between devices. A theoretical analysis of extended-resonance combiners is presented, followed by experimental data from an eight-device power amplifier. This approach is adaptable to monolithic circuit-fabrication techniques and should be useful for millimeter-wave applications
