    Abstract: A communication device may include a millimeter wave (mm-wave) antenna array having antenna elements, a mm-wave element (e.g. lens), and one or more transceivers (e.g. first and second transceivers). The mm-wave lens may be configured to adjust the first beam and the second beam as the first and second beams pass through the mm-wave lens. The first transceiver can selectively couple to the antenna elements, the first transceiver being configured to drive a first selected antenna element of the antenna elements to transmit a beam from the selected first antenna element. The second transceiver may selectively couple to the antenna elements, the second transceiver being configured to drive a second selected antenna element of the antenna elements to transmit a second beam from the selected second antenna element.

    Abstract: Techniques are described related to digital radio control and operation. The various techniques described herein enable high-frequency local oscillator (LO) signal generation using injection locked cock multipliers (ILCMs). The techniques also include the use of LO signals for carrier aggregation applications for phased array front ends. Furthermore, the disclosed techniques include the use of array element-level control using per-chain DC-DC converters. Still further, the disclosed techniques include the use of adaptive spatial filtering and optimal combining of analog-to-digital converters (ADCs) to maximize dynamic range in digital beamforming systems.

    Abstract: An antenna module and communication device containing the antenna module are disclosed. The antenna module is disposed in a metal cavity. The antenna module includes a switched beam mm-wave antenna array having radiating elements separated by less than a wavelength of the radiating elements. The array is fed by a single transceiver chain. The array is disposed at the focal length of a low-profile mm-wave lens configured to steer the beam. A sub-10 GHz antenna is disposed closer to the opening of the cavity than the lens. The lens is a Fresnel Zone Plate lens having a focal length of less than about the wavelength of the beam, or a Saucer lens having shells of different refractive indexes and having a profile that is more than 6 times smaller than a Luneburg lens with a same focal length.

    CPC classification number: H03H7/1758

    Abstract: A filter includes a plurality of filtering paths. The plurality of filtering paths is driven by a corresponding plurality of local oscillator (LO) signals associated with an LO frequency. Each of the LO signals has a phase of a plurality of phases. Each filtering path of the plurality of filtering paths includes a plurality of signal generation branches. The plurality of signal generation branches is configured to receive a harmonic LO signal based on a fraction of the LO frequency, and generate an LO signal of the corresponding plurality of LO signals associated with the LO frequency using the harmonic LO signal.
