Abstract
Abstract An extra high frequency (EHF or millimeter wave length) translating device for detecting, multiplying frequency or mixing waves includes an extra high frequency cut off input transmission line mechanically joined by a housing in which there is a cavity loaded with a removable insert. The insert contains a wave coupling element such as a diode mixer, multiplier, detector, etc. and is so mounted in the insert that it couples with the electric field of waves in the input line and is electrically connected with the relatively lower cut off frequency line output line. The insert also contains a choke so disposed that the extra high frequency waves conducted by the input line do not couple to the output line and so the output taken from the relatively low frequency cut off output line is substantially free of extra high frequency signals.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
151 words
In a high frequency wave translating device including an input wave guide transmission line structure designed for conducting millimeter waves and an output coaxial transmission line structure, means coupling said input and output structures comprising, a housing assembly which forms a part of the input and output structures, a cavity in the housing, a removable insert which fits into the cavity, said insert containing intersecting waveguide and coaxial wave conducting structures designed to match said input and output structures respectfully when the insert is inserted into the cavity, a wave translating element mounted at said intersection in the insert so that when inserted, the element couples electrically with both the input and output structures, and a removable wave choke formed by a dielectric piece defining a wave cavity at the inserted end of said insert for preventing millimeter waves conducted by the input structure from being conducted to the output structure.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
50 words
A device as in claim 1 and in which, the axes of the input waveguide and output coaxial transmission lines, are perpendicular and the element at the intersection couples to the electric field of waves conducted by the waveguide and electrically connects to the center conductor of the coaxial line.
Claim 4
Dependent Claim
55 words
A device as in claim 2 and in which, the choke is a quarter wave length waveguide section extending radially from the coaxial transmission line and is defined by the dielectric piece abutting the insert inside the housing and a contiguous conductive disc that fits into the housing cavity at the end of the insert.
Claim 5
Dependent Claim
49 words
A device as in claim 1 and in which, the cavity for the insert is directed transverse to the axis of the input waveguide and the insert contains an opening in which the element is mounted, said opening being in registry with and forming a continuation of the waveguide.
Claim 6
Dependent Claim
23 words

Claim 10
Dependent Claim
46 words
A device as in claim 4 and in which, the cavity in the housing accommodates a number of different inserts each containing a different type of element, whereby the element in the device can be readily changed by removing one insert and replacing it with another.
Claim 11
Dependent Claim
53 words
A device as in claim 4 and in which, the insert is generally cylindrical in shape and inserted into the housing along the axis of the housing cavity, the said housing cavity axis being transverse to the axis of the input wave guide and parallel to the axis of the output coaxial line.
Claim 12
Dependent Claim
49 words
A device as in claim 10 and in which, the cylindrical insert is formed of a cylindrical cOnductor transversly slotted to define the opening and containing a center conductor at the inserted end and an adjusting screw at the other end with the element connected to the adjusting screw.
Claim 13
Dependent Claim
48 words
A device as in claim 11 and in which, the housing includes two abutting cylindrical subassemblies one containing a coaxial connector which forms a portion of the output coaxial line and the other containing the insert, the waveguide, the choke and the initial portion of the output line.
Claim 14
Dependent Claim
26 words
A device as in claim 1 wherein, the dielectric piece is disc shaped and abuts the inserted end of the insert defining a coaxial wave choke.
