Surface-mounted millimeter wave signal source with ridged microstrip to waveguide transition
First Claim
1. 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.

Abstract
A surface-mountable mm-wave signal source is provided. The surface-mountable mm-wave signal source comprises: a conductive metal base; a mm-wave signal source disposed over an upper portion of the metal base; a first radio frequency transmission line carrying a quasi-TEM signal from the mm-wave signal source, which is disposed over an upper portion of the metal base and proximate the signal source; a first mode transformer at least partially integrated into the upper portion of the metal base to convert the quasi-TEM signal carried by the planar transmission line into a rectangular waveguide mode signal; a waveguide well having upper and lower ends disposed within the base for carrying the rectangular waveguide mode signal from an upper portion of the base to a lower portion of the base; and a second mode transformer at least partially integrated into the lower portion of the base to convert the rectangular waveguide mode signal to a quasi-TEM signal within a second radio frequency transmission line. The mm-wave signal source preferably operates in a frequency range of from 35 to 94 GHz, more preferably a frequency range of 70 to 80 GHz.
