Metallized plastic high radio frequency integrated waveguide

A transceiver comprising:

• an integrated waveguide comprising:
• a first substrate comprising a first plastic layer having on a first inward-facing surface, a first portion of a waveguide feature formed on the first inward-facing surface, and a metal layer disposed on the first inward-facing surface, and
• a second substrate comprising a second plastic layer having a second inward-facing surface, a second portion of a waveguide feature formed on the second inward-facing surface, and a metal layer disposed on the second inward-facing surface;
• and
• a housing wherein at least a portion of the integrated waveguide is disposed,
• wherein the first substrate and the second substrate are assembled to define an integrated waveguide feature defined by an assembling of the first portion of the waveguide feature and the second portion of the waveguide feature.

An integrated waveguide comprising:

• a first substrate comprising
• a first plastic layer having a first inward-facing surface and a first outward-facing surface,
• a metal layer disposed on the first inner-facing surface, and
• a metal layer disposed on the first outward-facing surface;
• and
• a second substrate comprising
• a second plastic layer having a second inward-facing surface and a second outward-facing surface,
• a metal layer disposed on the second inner-facing surface, and
• a metal layer disposed on the second outward-facing surface,
• wherein
• the first substrate and the second substrate are assembled to define an integrated waveguide feature defined by an assembling of the first portion of the waveguide feature and the second portion of the waveguide feature,
• dimensions of the first and second plastic layers are predefined, and the first and second plastic layers are dimensioned within +/−10 mils for each predefined dimension,
• the first plastic layer is formed using an injection mold assembly and the metal layer of the first plastic layer is disposed by copper electroplating, and
• the first plastic layer and the second plastic layer comprise an acrylonitrile-butadiene-styrene (ABS) plastic that minimally contracts or expands over a temperature range of −40° C. to +50° C.
