Abstract : The patent application describes an ultra broad band RF phase shifter which includes a variable generator providing sine and cosine signals. A preselected RF signal is split into two equal phase and equal amplitude signals. One of the split signals is modulated by the sine signal and the other by the cosine signal to provide two modulated in-phase RF signals whose amplitude relation is orthogonal (i.e., linear polarization). The two modulated signals are circularly polarized which imposes an orthogonal phase relationship thereupon. By variation of the sine, cosine generator a phase rotation results.
