Radio frequency circuit and communication device

A radio frequency circuit configured to transfer a radio frequency signal of a first communication system and a radio frequency signal of a second communication system, the second communication system being different than the first communication system, the radio frequency circuit comprising:

• a first transfer circuit comprising a first filter and a second filter;
• and
• a second transfer circuit comprising a third filter and a fourth filter, wherein
• a passband of the first filter and a passband of the third filter at least partially overlap each other,
• a passband of the second filter and a passband of the fourth filter at least partially overlap each other,
• the first filter is configured to transfer the radio frequency signal of the first communication system,
• the third filter is configured to transfer the radio frequency signal of the second communication system,
• the second filter is configured to transfer one of the radio frequency signal of the first communication system or the radio frequency signal of the second communication system, and
• the fourth filter is configured to transfer the other of the radio frequency signal of the first communication system or the radio frequency signal of the second communication system.
