Abstract
A millimeter wave wireless (M2W2) interconnect is used for transmitting and receiving signals at millimeter-wave frequencies for short-range wireless communication with high data rate capability. The transmitter and receiver antennae may comprise an on-chip differential dipole antenna or a bond-wire differential dipole antenna. The bond wire differential dipole antenna is comprised of a pair of bond wires connecting between a pair of pads on an integrated circuit (IC) die and a pair of floating pads on a printed circuit board (PCB).
Claims26
A wireless interconnect for transmitting and receiving signals at specified frequencies for short-range communication with high data rate capability, comprising:
- a transmitter for modulating a carrier signal with an input data stream, wherein the modulated carrier signal is then fed to a transmitter antenna that radiates the modulated carrier signal;
- and
- a receiver for receiving the radiated carrier signal at a receiver antenna and for converting the received carrier signal to a full swing digital signal as an output data stream;
- wherein the transmitter and receiver use asynchronous modulation and differential signaling for communicating between integrated circuit chips or printed circuit boards;
- and
- wherein the receiver only detects changes in amplitude of the carrier signal and does not detect changes in phase or frequency variations of the carrier signal, and thus the receiver operates asynchronously without a phase-lock loop, while eliminating any need for carrier signal re-generation.
