Abstract
A coupler circuit includes: a signal line disposed between a first terminal and a second terminal; a coupling line disposed between a coupling port and an isolation port such that the coupling line is coupled to the signal line and is configured to extract a coupling signal from the signal line; and a coupling adjusting circuit connected to the coupling port and the isolation port, and configured to reduce changes in an amount of coupling according to a change in a frequency band of a signal passing through the signal line.
