Latest Patents

David holds a patent for a system titled "Forward and reverse VSWR insensitive power detection using phase shifting and harmonic filtering." This invention provides a method for detecting both forward and reverse power of a power amplifier while addressing the harmonics created by the amplifier. The forward power detection system utilizes detection signals from both in-phase and quadrature-phase amplifier legs. By applying a phase shift to these signals, the system ensures that forward components are in-phase and reverse components are 180 degrees out-of-phase. The combined and filtered signals then yield an accurate indication of forward power. Similarly, the reverse power detection system employs a phase shift to provide a signal indicative of reverse power.
