Phase shifter with broadband and phase array module using the same

摘要

A phase shifter with broadband and a phase array module using the same are provided. The phase shifter includes at least one phase shifting unit. The phase shifting unit includes a first switch, a first capacitor, a second capacitor, a first inductor, a second switch, a second inductor, a first resistor and a second resistor. The first capacitor is connected between the first inductor and a second end of the first switch. The second capacitor is connected between the first inductor and a third end of the first switch. A second end of the second switch is connected to a ground end. The two ends of the second inductor are respectively connected to a ground end and a third end of the second switch. The first inductor is connected between the first capacitor and the third end of the second switch.
