Latest Patents
One of Mansell's latest patents is titled "Spurious energy correlation for control of linear power amplifiers." This invention focuses on a control system for a linear feed-forward amplifier, utilizing the ratio of measured spurious energy. The system incorporates measuring receivers that are connected to two monitoring points to assess the spurious energy content in the error signal and at the main output of the amplifier. By measuring the ratio of these detected spurious signals, the control system optimizes the settings for distortion cancellation. Additionally, this technique can be adapted to control an adaptive predistorter before the main amplifier.
Another significant patent is "System and method for forward path gain control in a digital predistortion linearized transmitter." This invention outlines a method for managing the gain in the forward signal path of a digital predistortion linearizer. The loop gain of the predistortion system is driven to unity, allowing for accurate gain control through a separately controlled constant-gain observation path. The invention effectively balances digital gain from the predistortion function and analog gain from a Voltage Variable Attenuator (VVA) in the transmitter. It compensates for the non-linear behavior of the VVA, ensuring predictable performance even under varying conditions.
