Abstract
Power combining methods and devices for tunnel diode oscillators using the infinite wavelength phenomenon observed in composite right/left-handed (CRLH) meta-material lines are described. One implementation utilizes a series combiner composed of zero degree lines, with each oscillator output port connected directly to the line and combined in-phase, to equally combine the power in phase. In a second implementation, a section of zero degree transmission line implements a stationary wave resonator with oscillators loosely coupled to the resonator, where the wave amplitude and phase are constant along the line. In one test of this second implementation a maximum power combining efficiency of 131% was obtained with the zeroth order resonator with two tunnel diodes oscillators at 2 GHz.
