Abstract
A device for connecting plural oscillators to a single output port without he use of power dividers, switches or multiplexing filters. The plural oscillators produce multiple frequencies with only one oscillator operating at a given time. The oscillators are mounted in shunt waveguide cavities along a central waveguide manifold at distances from the central waveguide manifold and waveguide end so as not to affect the operating oscillator.
Claims7
A multiple frequency oscillator comprising:
- a waveguide housing having a waveguide cavity therein, said waveguide cavity comprising a main waveguide manifold cavity and n shunt waveguide cavities extending from said main waveguide manifold cavity;
- and
- n oscillators each having a different center frequency of oscillation and each being mounted within one of said n shunt waveguide cavities, each of said oscillators having an on and an off condition and each appearing as a highly reactive impedance when in said off condition, each of said n oscillators being so positioned within its respective said shunt waveguide cavity such that when each said oscillator is in said off condition, it appears as a substantially open circuit at the center of said main waveguide manifold cavity.
