Phase shifters are devices used to change the phase of a transmission network. An ideal phase shifter has very small insertion loss and almost the same loss in different phase states. This is to achieve amplitude balance. Most phase shifters are reciprocal networks, which means that there is a phase shift when the signal is transmitted in different directions. Phase shifters can be electrically, optically, magnetically, mechanically, etc.
I made a 20GHz microstrip switch linear phase shifter with a 90-degree phase shift. The phase is very accurate. It has a bandwidth of 500MHz, but the insertion loss is relatively poor. I wonder if anyone has done this before, let's discuss it.
