Abstract
Apparatus ( and ) and method are provided for minimizing power losses when combining rf signals in conductors ( A, B, A, and B) that are at quadrature phase angles. The method includes: mixing rf signals that are at quadrature phase angles; producing a dc voltage from the mixing step that is a function of a phase-angle deviation from quadrature; and correcting the phase-angle deviation. The correcting step includes tuning a length of a selected one of two rf conductors. Preferably, the method also includes equalizing amplitudes of the rf signals. When the method includes series connecting upper (Q ) and lower (Q ) solid-state current devices, the step of equalizing amplitudes of the rf signals includes adjusting a bias voltage of one (Q ) of the solid-state current devices.
