Phase Shifter
Phase shifter is a 2-port network which could change the output phase according to the outer analog command. There are many circuits for phase shifter which can be divided by control type into digital phase shifter and continuously adjustable phase shifter that can turn out to be digital phase shifter after numeralization on the tuning voltage;or by the working mode into switching line phase shifter and load line phase shifter。The 2 modes have their own advantages and disadvantages respectively.The phase of switching line phase shifter is dispersible which means there is a linear relationship between the Dephasing and ferquency but the insertion loss varies little at different phase while the load line phase shifter is the contrary
