Abstract
A system and method for establishing a beam forming phase reference line remote from an antenna system is taught. By providing a phase reference line at a selected position in the signal path the present invention allows for a beam forming matrix to be utilized in providing distributed amplification without requiring additional power sharing matrix arrangements. Moreover, disposing of the phase reference line at a selected point in the signal path according to the present invention allows for multi-mode communications wherein both switched beam and adaptive beam forming may be utilized.
