    Tuning of diodes using stubs

    Hi, The issue are these>.. I used a PIN diode tomake a phase shifter obtaining a 90 degrees phase shift.Now I have been told by my supervisor to tune using stubs. I have read in Pozar and Fooks how to do it.But I am thinking about it in this way. Since Double stubs tuning is used when the load...

    Microstrip on Microwave Office

    Hello , How can I design a phase shifter in MIcrowave Office. I am to use RT/Duroid as the dielectric...could anyone help with leads of the schematics....i knowi am to use 2 SPDT's at either ends of the transmission lines...it is to operate at 5GHz and have a phase shift of 45 degrees.
