    Hi, I'm a beginner. both here and designing.

    I'm working on a switched beam antenna that operates at 2.6 GHz. I need a phase shifter to change the phase of the output beams. I read a lot about phase shifter but seriusly, I don't know how to design or where to start :confused:

    The phase shifter has one input and two output. The desired two output is the combination of these:
    0 and 0
    0 and 90°
    0 and -90°
    0 and -180°

    I was asked to refered to this circuit
    but this is a variable phase shifter.

    can anybody help me how to design or point me where to start?
