POWER COMBINING OF OSCILLATORS BY INJECTION LOCKING

摘要

Injection-locking is employed to produce phase coherency among a plurality of otherwise free-running incoherent oscillators. The outputs from the injection-locked oscillators are successively coupled together by means of a succession of quadrature couplers whose transmission and reflection coefficients are a function of the amplitudes of the signals incident thereon. The output signal power derived from the last of said couplers is the sum of the powers of the individual oscillators.
