Abstract:
A surface-mounted mm-wave signal source comprising:a conductive metal base; a mm-wave signal source disposed over an upper portion of said metal base; a first radio frequency transmission line disposed over said upper portion of said metal base and.proximate said signal source, said transmission line carrying a quasi-TEM signal from said mm-wave signal source; a first mode transformer at least partially integrated into said upper portion of said metal base to convert said quasi-TEM signal carried by said planar transmission line into a rectangular waveguide mode signal; a waveguide well having upper and lower ends disposed within said base for carrying said rectangular waveguide mode signal from said upper portion of said base to a lower portion of said base; a second mode transformer at least partially integrated into said lower portion of said base to convert said rectangular waveguide mode signal to a quasi-TEM signal within a second radio frequency transmission line oriented perpendicularly to said waveguide well.
