Abstract:

An RF interconnection between RF Printed Wiring Boards (PWBs) includes a waveguide transmission line coupled between the RF PWBs. The waveguide feeds are provided as integral parts of each PWB. In one embodiment, the waveguide interconnecting the PWBs is provided as an integral part of a support structure which supports the PWBs. By providing the interconnecting waveguide and the feeds at each end of the waveguide as integral pieces of other already existing structures, a reliable, low cost RF interconnection between RF PWBs having relatively few separate pieces is provided.
