Abstract:
In one example, a signal processing circuit including a directional coupler and a termination part is disclosed. The directional coupler includes a main line as a transmission path of an RF signal and a sub-line constituting a coupled line together with the main line. The termination part includes devices connectable between ground and a first port at an end of the sub-line. The signal processing circuit switches, depending on a frequency of the RF signal, the devices of the termination part to be connected to the first port. The phase of a return signal of a signal input as a coupling signal to the termination part via the first port is opposite to the phase of an isolation signal supplied to a second port at the other end of the sub-line and connected to an output port of the coupling signal.

Claim (Index 9):
The signal processing circuit according to  claim 8 , wherein\n when outputting the coupling signal corresponding to a traveling wave component of the RF signal from the output port, the control circuit turns off the third switching element, turns on the fourth switching element, and controls the first switching elements.
