A broad-band analog phase shifter design on I-Q vector modulator

Phase shifter is widely applied in some area, including communication and radar. In the study, the principle of broadband analog phase shifter on I-Q modulating is introduced, which is validated by the theory design using Ansoft serenade. The microwave phase shifter on I-Q modulating broadband is simulated and the corresponding entity is designed. Finally, some test are done to the phase shifter, and we sum up the design experience, all those can provide some design experience with the engineers.
