Broadband millimeter-wave front-end integrated circuit

摘要

According to one embodiment, a millimeter-wave front-end integrated circuit comprises an array of mm-wave transceivers, wherein each of the mm-wave transceivers is a coherent mm- Transmit and receive wave signals. The mm-wave front-end IC chip further includes a wideband frequency synthesizer coupled to the mm-wave transceivers. A full-band or wideband frequency synthesizer generates a local oscillator (LO) signal and provides it to each of the mm-wave transceivers, allowing the mm-wave transceiver to mix, modulate, and/or demodulate mm-wave signals. . An array of mm-wave wideband transceivers and a wideband frequency synthesizer can be implemented in a single IC chip as a single mm-wave front-end IC chip or package.
