Abstract
Abstract A waveguide casing has a transverse bore through its top and bottom broad walls. A diode is disposed between a diode holding chuck and a slideable collar disposed in the top wall bore. The slideable collar is urged toward the diode by one end of a compression spring whose other end bears against a fixed collar in the upper bore. The chuck is threadably disposed in a chuck holder which itself is threadably disposed in the bottom wall bore.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
219 words
A millimeter wave device comprising: a. case means defining a waveguide passageway; b. semiconductor positioning means disposed in said case means and adjustable relative thereto along an axis substantially normal to said passageway; c. semiconductor contacting means in said case means and disposed substantially opposite said positioning means, said contacting means having a fixed pin portion and a movable collar portion movable on said pin portion along said axis of said positioning means at a predetermined distance from the semiconductor positioning means in cooperation therewith; the positioning means comprising outer and inner concentric post members providing respectively a first adjustment for varying the penetration of the outer post member into the waveguide passageway and a second adjustment for establishing a predetermined distance between one end of the outer post member and the movable collar portion of the contacting means; d. semiconductor means disposed between said positioning means and said movable collar portion of said contacting means, and communicating with said waveguide passageway; and c. bias circuit connector means coupled to said movable collar portion of said contacting means, said connector means and positioning means being adapted for coupling to a bias circuit for supplying bias energy to said semiconductor means, said contacting means effecting with said case means a filter for blocking radio frequency energy from said bias circuit.
Claim 2
Dependent Claim
219 words
A millimeter wave device comprising: a. case means defining a waveguide passageway; b. semiconductor positioning means disposed in said case means and adjustable relative thereto along an axis substantially normal to said passageway; c. semiconductor contacting means in said case means and disposed substantially opposite said positioning means, said contacting means having a fixed pin portion and a movable collar portion movable on said pin portion along said axis of said positioning means at a predetermined distance from the semiconductor positioning means in cooperation therewith; the positioning means comprising outer and inner concentric post members providing respectively a first adjustment for varying the penetration of the outer post member into the waveguide passageway and a second adjustment for establishing a predetermined distance between one end of the outer post member and the movable collar portion of the contacting means; d. semiconductor means disposed between said positioning means and said movable collar portion of said contacting means, and communicating with said waveguide passageway; and c. bias circuit connector means coupled to said movable collar portion of said contacting means, said connector means and positioning means being adapted for coupling to a bias circuit for supplying bias energy to said semiconductor means, said contacting means effecting with said case means a filter for blocking radio frequency energy from said bias circuit.
Claim 3
Dependent Claim
83 words
The device of claim 1 in which said contacting means comprises: a. a fixed collar portion supporting said fixed pin portion and secured relative to but insulated from said case means; and b. resilient force bias means disposed between said fixed and movable collar portions for urging said movable collar portion into good electrical contact with said semiconductor means, said fixed and movable collar portions serving as one-quarter wavelength chokes which complete the radio frequency circuit through said case means for filtering purposes.
Claim 4
Dependent Claim
38 words
The device of claim 1 in which the semiconductor means comprises a switching diode, the outer post member is threadably mounted in the case means, and the inner post member is threadably mounted within the outer post member.
Claim 5
Dependent Claim
228 words
A millimeter wave device comprising: a. case means defining a waveguide passageway; b. semiconductor positioning means disposed in said case means and adjustable relative thereto along an axis substantially normal to said passageway; c. semiconductor contacting means in said case means and disposed substantially opposite said positioning means; said contacting means having a fixed collar portion supporting a fixed pin portion and secured relative to but insulated from said case means, a movable collar portion movable on said pin portion along said axis of said positioning means at a predetermined distance from the semiconductor positioning means in cooperation therewith, and resilient force bias means disposed between said fixed and movable collar portions for urging said movable collar portion into good electrical contact with said semiconductor means, said fixed and movable collar portions serving as one-quarter wavelength chokes which complete the radio frequency circuit through said case means for filtering purposes and effecting with said case means a filter for blocking radio frequency energy from said bias circuit; D. semiconductor means disposed between said positioning means and said movable collar portion of said contacting means, and communicating with said waveguide passageway; and e. bias circuit connector means coupled to said movable collar portion of said contacting means, said connector means and positioning means being adapted for coupling to a bias circuit for supplying bias energy to said semiconductor means.
Claim 6
