    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: A voltage controlled oscillator (VCO) circuit is disclosed. The VCO circuit comprises a VCO tuning circuit comprising a primary inductive coil. In some embodiments, the VCO tuning circuit is configured to generate a VCO output signal at a first resonance frequency. The VCO circuit further comprises a filter circuit comprising a secondary inductive coil. In some embodiments, the filter circuit is configured to resonate at a second, different, resonance frequency, in order to filter a noise associated with the VCO tuning circuit. In some embodiments, the primary inductive coil associated with the VCO tuning circuit and the secondary inductive coil associated with the filter circuit are concentrically arranged with respect to one another. Further, in some embodiments, the primary inductive coil associated with the VCO tuning circuit and the secondary inductive coil associated with the filter circuit are magnetically decoupled with respect to one another.

    Abstract: Techniques are described related to digital radio control, partitioning, and operation. The various techniques described herein enable high-frequency local oscillator signal generation and frequency multiplication using radio-frequency (RF) digital to analog converters (RFDACs). The use of these components and others described throughout this disclosure allow for the realization of various improvements. For example, digital, analog, and hybrid beamforming control are implemented and the newly-enabled digital radio architecture partitioning enables radio components to be pushed to the radio head, allowing for the omission of high frequency cables and/or connectors.
