The asymmetric dual directional coupler includes a main line having an input port and an output port, multiple coupled lines separated from the main line, the coupled lines having different lengths for providing different coupling factors, respectively, where each coupled line has first and second ports. The switching circuit selectively applies one of the different coupling factors of the coupled lines, depending on frequency of the RF signal in relation to a predetermined threshold frequency, while coupling a portion of forward power or reverse power of the RF signal to a coupling reading port, to mitigate power loss in an upper frequency range of the RF signal, while satisfying coupling criteria."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wideband dual directional coupler","description":"A directional coupler device includes an asymmetric dual directional coupler for receiving a radio frequency (RF) signal and a switching circuit.
