摘要: Disclosed herein are a directional coupler which is implemented with strip lines for signal coupling and inter-digital capacitors for phase compensation, and a dual-band transmitter using the same. The directional coupler includes a first transmission device, a first directional coupling device for coupling a part of a signal from the first transmission device, a first inter-digital capacitor connected between the first transmission device and the first directional coupling device, a second transmission device, a second directional coupling device for coupling a part of a signal from the second transmission device, and a second inter-digital capacitor connected between the second transmission device and the second directional coupling device.
