Abstract
Abstract A removable diode package for mounting beam-lead diodes in coaxial, stripline or waveguide microwave circuits is described. The diode package is capable of operation at frequencies above 40 GHz. A low-dielectric polyimide insulating washer is used to reduce parasitic elements normally associated with diode packages at microwave and millimeter frequencies.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
114 words
A diode package suitable for use at frequencies up to above 40 GHz for mounting a beam-lead diode in a stripline, coaxial or waveguide assembly, the diode having a first and second electrode, the package comprising: an electrically conductive tuning screw having at least one flat face; a gold ribbon mounted on said flat face of said tuning screw and connected to the first electrode of the beam-lead diode; an annular insulating member having a low dielectric constant surrounding the beam-lead diode and mounted on said flat face of said tuning screw; and an electrical conducting member mounted on said annular insulating member, said second electrical member being electrically connected to said second electrode.
Claim 2
Dependent Claim
