Forward and reverse VSWR insensitive power detection using phase shifting and harmonic filtering

摘要: A system for detecting both forward and reverse power of a amplifier in the presence harmonics created by is provided. detection receives signals from an in-phase leg quadrature-phase amplifier. The applies phase shift to such that components are essentially in-phase, 180 degrees out-of-phase. shifted then combined filtered provide signal indicative power. In similar fashion,
