Abstract

A signal coupler (100) comprising: a main-transmission-line (114) that extends in a longitudinal direction within a substrate (102) between an input port and an output port; and a coupled-transmission-line (116) that extends in the longitudinal direction within the substrate (102) between a coupled port and a termination port. The coupled-transmission-line (116) is in a second layer (110). The main-transmission-line (114) comprises a first-portion (120) in a first layer (108), a second-portion (122) in a second layer (110), and a third-portion (124) in a third layer (112). At least part of the first-portion (120) is spaced apart from the coupled-transmission-line (116) in a depth direction. At least part of the second-portion (122) is spaced apart from the coupled-transmission-line (116) in the depth direction. At least part of the third-portion (124) is spaced apart from the coupled-transmission-line (116) in the depth direction.
