RF Amplifier Data Stream Alignment with Low-Skew Clocking

The patent merges multiple separate clock trees into a unified clock distribution system that provides a common reference clock signal to all data streams. This is achieved by introducing a master clock signal that distributes timing references to both radio-frequency and control signal paths, ensuring synchronized timing while maintaining independent signal processing capabilities.

The patent introduces delay compensation circuitry as an intermediary element between the clock distribution system and the data streams. This intermediary component actively adjusts and equalizes the timing of different data streams to compensate for path delays, ensuring that radio-frequency and control signals arrive at the power amplifier input simultaneously without requiring complete clock tree integration.

The patent applies delay compensation locally at specific critical points in the signal path where timing misalignment occurs, rather than implementing a global timing adjustment system. Delay compensation circuitry is strategically placed in the control signal path to match the timing of radio-frequency signals, providing precise timing correction only where needed without adding complexity throughout the entire system.

The patent dynamically adjusts timing parameters such as delay values and clock phase offsets to compensate for temperature and voltage variations. By making timing parameters adjustable and adaptive rather than fixed, the system maintains precise timing alignment under varying operating conditions without requiring a completely complex reconfigurable circuit architecture.
