  • Publication number: 20150002355
    Abstract: A first module and a second module are formed on a complementary metal-oxide-semiconductor (CMOS) chip substrate. The first module is to serialize and de-serialize a data signal. The second module is to up-convert and down-convert the data signal to and from the first module. An antenna is coupled to the second module and integrated onto the CMOS chip substrate. The antenna is coupleable to a hollow metal waveguide (HMWG). The first and second modules are arranged for proximity to the antenna to avoid substantially degrading the data signal at millimeter wave frequencies in migrating the data signal between the first module and the antenna.
