Abstract
An integrated coupler may vertically integrate a hybrid coupler and a directional coupler. The hybrid coupler may include a first quarter-wave metallic strip dielectrically coupled to a second quarter-wave strip. The directional coupler may include the second quarter-wave metallic strip dielectrically coupled to a third metallic strip. The first quarter-wave metallic strip may receive a first input signal. The second quarter-wave metallic strip may receive a second input signal, and it may superimpose the first quarter-wave metallic strip along a vertical space, so as to combine power received from the first input signal and the second input signal to form an output signal. The third quarter-wave metallic strip may superimpose the second quarter-wave metallic strip along the vertical space, so as to sample the output signal of the second quarter-wave metallic strip.
