Abstract
A wideband microwave diplexer is provided which includes a waveguide section characterized by a longitudinal dimension, and defining first and second longitudinally spaced ports, for propagating microwave power substantially within a first lower frequency band between said first port and said second port; coupling resonator means for coupling microwave power substantially within a second higher frequency band between said waveguide section and a coaxial transmission line; and band stop filter means for substantially preventing microwave power substantially within the second frequency band from propagating to said second port.
