    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: For example, a phase shifter may include an input to receive an input clock signal having an input frequency and an input phase. For example, the phase shifter may include a quadrature phase-shift generator configured to generate a first signal and a second signal based on the input clock signal, the first and second signals having the input frequency, wherein a phase of the first signal is based on the input phase, wherein a phase of the second signal is shifted by a quadrature phase-shift relative to the phase of the first signal. For example, the phase shifter may include an output to provide an output based on the first signal and the second signal.
