Wireless printed circuit board assembly with integral radio frequency waveguide

A method of assembling a printed circuit board assembly for a high-speed, short-reach communication link, the method comprising:

• forming a printed circuit board comprising a plurality of layers, wherein forming the printed circuit board comprises defining a channel in at least one of the plurality of layers, and wherein the channel is configured to confine radio frequency waves therein;
• disposing a digital electronic component on the printed circuit board, wherein the digital electronic component is configured to convert between electrical signals and radio frequency signals;
• and
• forming a radio frequency antenna in communication with the digital electronic component and with the channel, wherein the antenna is configured to transmit radio frequency signals generated by the digital electronic component into the channel as radio frequency waves or to receive radio frequency waves via the channel and convey corresponding radio frequency signals to the digital electronic component.
