Integrated circuit package assembly including wave guide

摘要

Some embodiments herein relate to a transmitter. The transmitter includes an integrated circuit (IC) package including a first antenna configured to radiate a first electromagnetic signal therefrom. A printed circuit board (PCB) substrate includes a waveguide configured to receive the first electromagnetic signal and to generate a waveguide signal based thereon. A second antenna can be electrically coupled to the waveguide and can radiate a second electromagnetic signal that corresponds to the waveguide signal. Other devices and methods are also disclosed.

1. A method of manufacturing an integrated circuit (IC) package assembly, comprising:
providing a printed circuit board (PCB) substrate; forming a patterned metallic layer on a lateral surface of the PCB substrate, wherein the patterned metallic layer is suitable for carrying electrical signals thereon; forming an aperture that extends through the PCB substrate along an aperture axis, wherein the aperture defines inwardly-facing sidewalls in the PCB substrate; forming a first conductive layer to conformally cover the inwardly-facing sidewalls and laterally circumscribe the aperture; and adhering an IC package to the PCB substrate, wherein the IC package includes an antenna proximate to the aperture axis and configured to generate an electromagnetic wave, and wherein the first conductive layer is arranged to induce a time-varying signal thereon, wherein the time-varying signal is indicative of the power of the electromagnetic wave over time.
