LOCKED HYBRID JUNCTION POWER COMBINER

摘要

TITLE LOCKED HYBRID JUNCTION POWER COMBINER INVENTOR Jan Nigrin A locked hybrid junction power combiner comprises in its simplest version a single hybrid junction(0.degree., 180.degree. and 90.degree.) and an appropriate phase shifting element combining three one port oscillators (one master oscillator strongly locking the other oscillators). The combiner can be extended to combine any odd number of oscillators. Combining efficiency approaching 100% and locking figure of merit exceeding that of the master oscillator have been experimentally observed. Isolating the master oscillator from the hybrid by a circulator, the LHJ combiner can generate high microwave powers with spectral purity of the master oscillator; e.g. Impatt diode power capabilities may be combined with Gunn diode spectral purity. The combiner with an ordinary E-H waveguide hybrid junction can be employed to generate ultrahigh microwave powers by combining high power tube sources.
