Abstract
Low loss high directivity signal coupler-dividers use two additional waveguide sections coupled using traversing holes with a main waveguide section, which carries a longitudinal slot, into which a metallic tuning probe is inserted and precisely positioned. The coupler-divider allows vector load pull and sampling a portion of the signal to amplify and inject back through the tuner section to create a compact hybrid tuner for sub-THz tuning frequencies.
Claims10
A waveguide load pull tuner for hybrid load pull comprising:
- a waveguide load pull tuner section, and
- a waveguide directional signal coupler-divider section,
- wherein
- the waveguide load pull tuner section comprises:
- a main waveguide transmission line having
- a test port and an idle port, and
- a slot along a longitudinal axis, which is at least one half a wavelength long at a lowest frequency of operation, and
- a conductive tuning probe remotely insertable perpendicularly into the slot between withdrawal and maximum insertion depth and movable along the slot,
- and wherein
- the directional waveguide signal coupler-divider section comprises:
- two secondary waveguide transmission lines, a first secondary waveguide transmission line and a second secondary waveguide transmission line,
- each said first and second secondary waveguide transmission line each being attached to and coupled electro-magnetically with the main waveguide transmission line via a number of holes traversing the main and the first and second secondary waveguide transmission lines,
- and wherein
- the slot of the main waveguide transmission line, into which the tuning probe enters, is placed between the idle port and the coupler-divider section.
