Abstract :
This analog X-band phase shifter is made up of four variable gain amplifiers combined in parallel, and respectively in phase quadrature. The association of these amplifiers is equivalent to a sum of vectors in the complex plan ; by controlling the amplitudes of these vectors, the phase of the output signal can be controlled over a 360° range.
