    Abstract: A system for assigning a characterization and calibrating a parameter is disclosed. The system includes a frequency measurement circuit and a finite state machine. The frequency measurement circuit is configured to measure frequencies of an oscillatory signal and to generate a measurement signal including measured frequencies. The finite state machine is configured to control measurements by the frequency measurement circuit, to assign a characterization to a parameter based on the measurement signal, and to generate a calibration signal based on the characterized parameter.

    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.

    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.
