Abstract
1,201,947. Cavity resonators. NORTH AMERICAN ROCKWELL CORP. 11 Sept., 1968, No. 43285/68. Heading H1W. [Also in Divisions H2 and H3] In a parametric harmonic generator (see Divisions H3 and H2) in which a non-linearly reactive component 30 is situated in a rectangular waveguide section the pump frequency resonant cavity is defined by a shorting plane 16 and a pair of oppositely arranged channels 22, 22d. A second pair of channels 26, 26a are provided to prevent propagation of the idler frequency along the waveguide section 14 to input signal port 12. The two channels of each pair may be replaced by a single channel. An additional channel or channels may be provided between channels 22, 22a and 26, 26a to form a second cavity region and also a pair of channels between 26, 26a and port 12 to provide additional attenuation. Side channels 24 help to achieve desired propagating modes and suppress spurious modes.
