Abstract (en)
[origin: EP1863116A1] The coupler has a distributed line structure (20), whose transmission line (11`) conveys a main signal between terminal pairs (IN, DIR) of an end. A coupled line (12`) coupled with the line (11`) conveys a signal proportional to the main signal. A localized element structure (30) has two attenuators (31, 32) in series between a terminal (CPLD) of the coupler and a terminal pair (IPCLD) of the line (12`). A low-pass filter (35) is sandwiched between the attenuators and an attenuator (33) is sandwiched between a terminal (ISO) of the coupler and a terminal pair (IISO) of the line (12`).
