  • Slot-coupled microwave diplexer and coupler therefor
    Patent number: 4458217
    Abstract: A compact power coupler comprises a first waveguide short-circuited at one end, a resonant cavity slot-coupled to the shorted end of the first waveguide, and a coaxial transmission line coupled to the resonant cavity. Power at 6 gigahertz is coupled from the waveguide to the transmission line in a unit that is 3.5 inches long. Alternatively, a second waveguide can be slot-coupled to a narrow-wall of the first waveguide (a quarter-wavelength from the short-circuit) to couple 4 gigahertz power, thereby forming a compact diplexer.
