Wireless communication technology, apparatuses, and methods
Millimeter wave (mmWave) technology, apparatuses, and methods that relate to transceivers, receivers, and antenna structures for wireless communications are described. The various aspects include co-located millimeter wave (mmWave) and near-field communication (NFC) antennas, scalable phased array radio transceiver architecture (SPARTA), phased array distributed communication system with MIMO support and phase noise synchronization over a single coax cable, communicating RF signals over cable (RFoC) in a distributed phased array communication system, clock noise leakage reduction, IF-to-RF companion chip for backwards and forwards compatibility and modularity, on-package matching networks, 5G scalable receiver (Rx) architecture, among others.
1. An apparatus for a mobile device, the apparatus comprising:
a printed circuit board (PCB) that comprises a first layer and a second layer;
an integrated circuit (IC) chip that comprises a top level and a bottom level, wherein the IC chip comprises a transceiver and the IC chip is connected to the first layer of the PCB;
an antenna array that comprises a plurality of antenna elements configured within the first layer of the PCB and fed by feed transmission lines coupled to the transceiver; and
an IC shield, separated from the antenna array, that covers the IC to shield the antenna array from interference generated by the IC, and is connected to the PCB, wherein the IC shield is configured to act as a reflector and a ground reference for the antenna array.
2. The apparatus of claim 1 , further comprising a clearance volume between the PCB and the antenna array to prevent at least one antenna element from contacting the PCB.
3. The apparatus of claim 1 , wherein the transmission feed lines comprise metal traces.
4. The apparatus of claim 1 , wherein the PCB comprises a mother board.
5. The apparatus of claim 1 , wherein the IC chip further comprises at least one power amplifier (PA).
6. The apparatus of claim 5 , wherein the IC chip further comprises at least one low noise amplifier (LNA).
