ABSTRACT:
A method of fabricating a microwave waveguide component wherein a plurality of joinable thermoplastic members are first formed. The members, when joined, comprise a microwave waveguide component having an internal surface that is adapted to be plated. The thermoplastic members are then bonded together. Then, the internal surface is plated to form the finished microwave waveguide component. The present method forms microwave components from plated, injection molded thermoplastic and reaction injection molded thermosetting plastics. In particular, the plastic components made using the present invention exhibit comparable electrical performance, as measured by voltage standing wave ratio (VSWR) and insertion loss, decreased device weight and cost, and reliable and repeatable manufacturability when compared with devices formed using metals, conventional thermosetting plastics that have been metallized, and molded, plated and soldered thermoplastics.
