Radio-frequency circuit

A radio-frequency circuit comprising:

• a first switch circuit including a first selection terminal and a first common terminal connected to an antenna connection terminal;
• a first transmission filter having a passband including a transmission band of a first frequency division duplex (FDD) band;
• a first reception filter having a passband including a reception band of the first FDD band;
• and
• a phase adjustment circuit operatively coupled between the first common terminal and the first transmission filter;
• wherein the first switch circuit and the phase adjustment circuit are configured to:
• provide a first signal path between the first common terminal and the first transmission filter in a first mode of operation such that a first reflection phase of the reception band is presented at the first common terminal;
• and
• provide a second signal path between the first common terminal and the first transmission filter in a second mode of operation such that a second reflection phase of the reception band is presented at the first common terminal, the second reflection phase being different from the first reflection phase, wherein an amount of phase variation in the transmission band provided by the first signal path is smaller than an amount of phase variation in the transmission band provided by the second signal path.
