Abstract: A switch-type phase shifter including a phase shifting unit is provided. The phase shifting unit includes two half circuits and a first switch connected to the half circuits and receiving a first control signal. Each half circuit includes a first variable capacitor, a second variable capacitor, a second switch and a variable inductor. The two ends of the first variable capacitor are coupled to the input and the control nodes of the half circuit respectively. The two ends of the second variable capacitor are coupled to the output and control nodes of the half circuit respectively. The first and second ends of the second switch are coupled to the output and input nodes respectively, and the third end thereof is coupled to the control node and receives a second control signal. The two ends of the variable inductor are coupled to the input and output nodes respectively.

Abstract: 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.
