Thin-film broadband coupler |
摘要 |
A thin-film coupler with a carrier substrate (1) and two strip lines disposed thereon, of which one represents the main coupler loop (2) and one the auxiliary coupler loop (3). The use of inexpensive carrier substrate materials and a compact construction are made possible through an integration of a strip line, a coil, or an LC combination into the auxiliary coupler loop (3). The integration of these components (4) achieves a phase shift in the frequency of the signal coupled out so that a broadband coupler is obtained which exhibits an identical coupling at at least two frequencies.
